Season Five

1. Day For Knight

   When enthusiastic third-year medical student, Lucy Knight (new series star KELLIE MARTIN), begins her emergency room rotation at Chicago's County General Hospital, she quickly learns that her book knowledge does not necessarily help her perform procedures correctly. Although she impresses doctors with her ability to answer medical questions, her attempts to help patients are clumsy.

   Lucy meets Dr. Maggie Doyle (recurring guest star JORJA FOX) and works with second-year resident Dr. John Carter (series star NOAH WYLE). She also encounters Bernard Gamely (recurring guest star VINCE VIELUF), a lanky 24-year-old medical student. Head nurse Carol Hathaway (series star JULIANNA MARGULIES) notices Lucy's lack of confidence and befriends her.

   Placed on probation, Hathaway's fianci, Pediatric Emergency Fellow Dr. Doug Ross (series star GEORGE CLOONEY), must report every procedure he needs to perform to Acting Chief of Emergency Medicine Dr. Kerry Weaver (series star LAURA INNES). Meanwhile, a paramedic asks Dr. Mark Greene (series star ANTHONY EDWARDS), chief resident, to consider acting as the district medical director for EMS (Emergency Medical Service), a voluntary job. Greene's daughter, Rachel (recurring guest star YVONNE ZIMA), is living with him for the summer.

   In search of a new fellowship, surgical Resident Dr. Elizabeth Corday (series star ALEX KINGSTON) returns from an interview in Denver and reunites with her lover, Dr. Peter Benton (series star ERIQ LA SALLE). Benton tells Corday that his son's hearing test is postponed due to an ear infection. Benton hopes the baby's hearing loss is due to the infection. And attractive Roxanne Please (recurring guest star JULIE BOWEN), an insurance agent injured during her exercise workout, receives treatment at the emergency room.

2. Split Second

   A child dies after not receiving proper treatment at the scene of a karate accident. This motivates Greene to become an unpaid EMS director. A jubilant Hathaway gets a salaried registered nurse for her clinic. She chooses Lynette Evans (recurring guest star PENNY JOHNSON), a friendly, no-nonsense nurse practitioner.

   To save rent money, Carter lives in a medical student dormitory as a resident advisor. But his responsibilities to the students cause him not to get enough sleep. At the hospital, Weaver approves Carter's salary request. Carter confides to Weaver that his goal is to become chief resident next year.

   While visiting Corday at her apartment, Benton meets her father, Charles Corday (PAUL FREEMAN). Charles Corday wants his daughter to return home with him and join his cardiothoracic practice. Later, Corday flawlessly performs surgery while operating the Aesop robotic computer with Dr. "Rocket" Romano (recurring guest star PAUL McCRANE) assisting. She realizes that the only way she can stay at County General is to start over as an intern, which she eventually decides to do. The audiology test on Reese, Benton and Carla's infant son, reveals a severe to profound hearing loss. He'll need digital hearing aids. Benton is deeply disappointed and a little bit in denial.

   Two teenage boys with gunshot wounds are rushed to the emergency room. One of the boys, B.G. (KAREEM GRIMES), has a non-serious scalp laceration. But the other one, Lil 'Toine (CORY C. HARDRICT), sustained a severe wound which will require a colostomy. Trouble occurs when both of B.G.'s girlfriends visit him at the same time.

   Weaver appears disappointed when Ross' 30-day probation period ends. He gets an offer to do a rotation in the Pediatric Intensive Care Unit.
   

3. They Treat Horses, Don't They?

   Chief of staff Dr. Donald Anspaugh (recurring guest star JOHN AYLWARD) informs a disappointed Weaver that her official title has changed from acting chief of emergency medicine to interim chief. Greene agrees to be on the search committee to consider candidates to fill the interim position permanently. Despite Weaver's objections, Ross gets the job as the new pediatric emergency room attending doctor. He discovers a teenage girl, Dana (recurring guest star ASHLEY JOHNSON), has cancer of the leg and must defend her rights to her parents who want to amputate.

   Jeanie Boulet returns from her vacation ready to work. Benton discusses Reese's deafness with Carla (recurring guest star LISA NICOLE CARSON). Corday watches them and mistakenly thinks they're reuniting until Benton reluctantly tells her about Reese.

   Greene's daughter, Rachel, pleads with Greene to help a horse in a trailer outside the ambulance bay. He administers an enema. Rachel is proud of her father for helping the horse. Greene's first assignment as an EMS director places him in danger as he treats a dynamite-wired assailant with gunshot wounds. Greene wears a bomb suit and examines the patient. After paramedics rush the bomber to the hospital, Benton works on him, but the patient still has a detonator box entangled in his intestines. When the box starts to hiss, Benton cuts the intestines, removes the box and throws it in a corner. It explodes. No one is hurt.

   Carter saves an elderly woman and places her on a ventilator. He later finds out she is a DNR (do not resuscitate) and reluctantly removes her from the ventilator. A confused Lucy observes as Carter stays with his patient, who eventually dies. Roxanne Please returns to have her foot examined by Carter. She flirts with him. Later, at Carter's dorm room, Roxanne competently assembles his expensive stereo system and the young couple share a romantic moment as they slow dance.
   

4. Vanishing Act

   Weaver interviews for the job as permanent chief of emergency medicine. Greene gets bitten by a dog when he helps the paramedics at an accident scene. Hathaway discloses to Ross that she might be pregnant but later discovers she's not. Lucy misplaces a dead body as she transports it to the morgue. Her inability to start an IV is revealed during a crisis. Carter angrily reprimands Lucy for lying to him.

   Assigned to obnoxious surgical resident Dale Edson (recurring guest star MATTHEW GLAVE), Corday realizes that her abilities exceed what will be demanded of her as an intern. She corrects Dale's wrong answer when queried by Romano during surgery.

   Hathaway and Evans disagree on how to control a gang member, Bo (JERMAINE MONTELL), with multiple stab wounds who refuses to cooperate with police because he wants to exact his own revenge. He leaves the hospital and later returns with serious gunshot wounds.

   Jeanie treats a transplant patient experiencing liver rejection. The man is on the list for another transplant, but his blood alcohol level tests positive. If she divulges this knowledge to the transplant authorities, he most certainly will not receive a new liver. She also cares for a child with a heart problem, but because he's an illegal alien, he can't get the treatment he needs. Jeanie tells Ross she'd like to be his physician assistant in the pediatric emergency room.

   While Romano prepares to amputate Dana's leg, Ross succeeds in postponing the surgery for a few more days in order to better manage her post-surgery pain. This infuriates Romano.

   Benton keeps Reese's hearing disability a secret from his coworkers. During his first therapy session with his son, Benton realizes how difficult it will be to help Rees
   

5. Masquerade

   On Halloween night, Greene escorts an arrogant candidate for chief of emergency services, Dr. David Litvak (PHILIP CASNOFF - "Sinatra"), around the emergency room. Greene later divulges to Weaver that, even though Greene voted for her, Litvak has been elected as chief. Greene neglects to order a pregnancy test on an unmedicated schizophrenic mother-to-be, Coco (recurring guest star SHEILA KELLEY - "L.A. Law"), and administers a drug that can cause birth defects. To add to his terrible day, Greene discovers that his ex-wife, Jennifer (recurring guest star CHRISTINE HARNOS), and his daughter, Rachel, plan to relocate to St. Louis, Missouri. Greene realizes he's become very devoted to Rachel in the summer she has been with him.

   Ross enacts strict policy procedures for the pediatric emergency room that become impossible to enforce due to the huge volume of patients. Ross relents and allows Weaver to work on some of his patients. Weaver asks Carter to give a presentation the following day on one of his former cases. Carter shares responsibility for Lucy's inability to start an IV and is no longer mad at her. He places Lucy in charge of the Halloween party at the dormitory so he can do research for his presentation. But trouble occurs when two medical students take drugs with alcohol and almost die. Once again, Carter is disappointed in Lucy.

   Test results surprise Benton, Romano and Dale when Corday reports that the little girl they are operating on is genetically a boy. Later, Corday, anxious to celebrate Halloween, gets a pleasant surprise from Benton, who dresses like the '70s film character John Shaft for a special date
   

6. Stuck On You

   Because of the Halloween fiasco, Carter is terminated as resident advisor, and he packs his belongings in preparation for moving out of the dormitory. Roxanne helps Carter in his search for a new place to live. When Carter answers a newspaper advertisement and visits a house, he is surprised to see Weaver open the door.

   While on a paramedic ride-along, Greene risks his life rescuing a battered, homeless teenage male prostitute named Kevin (CHAD E. DONELLA). Greene tries to help Kevin reform his personal life and encourages him to take medication to help with a dangerous medical condition, but the teenager refuses. Anspaugh realizes that Corday is overqualified to intern with Dale, who knows less than Corday does, and agrees to let Benton take over as her resident. Benton's reluctant due to their personal relationship.

   When Weaver learns that Dr. Litvak refused the job as chief of emergency services, she becomes increasingly optimistic, knowing that she's the board's second choice. Anspaugh informs Greene that the committee wants a chief with a national reputation who can acquire research grants. Greene ultimately informs Weaver about the board's decision to reopen its search. Insulted, Weaver removes herself from the search and resigns as interim chief. Weaver refers Benton to a hearing specialist, Dr. Lisa Parks (deaf actress PHYLLIS FRELICH - Broadway show "Children of a Lesser God"), for Reese. Parks, who is deaf, uses sign language and an interpreter to communicate.

   Ross becomes overwhelmed by his paperwork responsibilities for the pediatric emergency room. Jeanie treats a girl who keeps getting injured while competing for world records with her father. Evans and Hathaway disagree on a birth-control issue. HARVEY KORMAN ("The Carol Burnett Show") guest stars as Stan Levey, a cantankerous old man Hathaway treats in the clinic
   

7. Hazed And Confused

   Now living in Weaver's basement, Carter awakens to her loud music from upstairs. At the hospital, Carter hesitates to evaluate Lucy's performance because he wants to be fair. Lucy records her thoughts concerning difficulties with Carter into her palmtop computer. Carter finds the computer, unintentionally hears Lucy's private notes and becomes very defensive. Greene forces Carter and Lucy to confront their problems with each other.

   Weaver derives enjoyment from seeing Anspaugh muddle through as interim chief. The committee interviews Dr. Amanda Lee (recurring guest star MARE WINNINGHAM - "The Thorn Birds"), who appears to be the first choice for the position as chief. At Corday's urging, Benton speaks with ENT (Ear, Nose and Throat) specialist Dr. David Kotlowitz (recurring guest star DENNIS BOUTSIKARIS), who advocates cochlear implants. But Kotlowitz's fanaticism only confuses Benton. An exhausted Corday, awake for over 24 hours, administers a potentially fatal dose of magnesium to a patient, who almost dies. This mistake gets Benton and her in trouble.

   Disappointed that she's not pregnant, Hathaway administers a laboratory test to make sure her hormone levels are normal. Meanwhile, a streetwise pregnant woman fakes pain in order to obtain a free ultrasound at the clinic. When the patient discovers the sex of her baby, it becomes obvious she'll get an abortion. A furious Hathaway yells at her.

   Jeanie solves the mystery of a sick baby. Pediatric anesthesiologist Dr. Alex Babcock (recurring guest star DAVID BRISBIN) argues with Ross over setting policy in the pediatric emergency room. Greene enjoys the male camaraderie at the fire station with the paramedics and fire fighters until they try to initiate him with a hazing ritual. Greene stays with Hathaway and Ross for the night while asbestos is removed from his apartment
   

8. The Good Fight

   This special episode primarily concerns one case. A father and daughter involved in a motor-vehicle accident arrive at the emergency room. The father, Gemmill (JOHN THADDEUS), received a minor scalp laceration. But his 7-year-old daughter, Corinna (NICOLETTE LITTLE), has a ruptured spleen and may need surgery. Carter administers to the little girl and begins a blood transfusion. Gemmill tells Lucy to call the girl's mother in Cleveland.

   During the transfusion, Corinna unexpectedly loses consciousness. The staff realizes that the blood was typed correctly but it wasn't cross-matched, and Corinna is having a hemolytic reaction--her immune system is destroying the red blood cells. When Lucy tries to talk to the father, he's gone!

   After talking on the telephone to Corinna's mother in Cleveland, Ohio, Lucy discovers that the father's real name is Nelson. Currently, in a bitter divorce battle with his wife, Nelson gave a false name to avoid prosecution for kidnapping his daughter. Meanwhile, the laboratory results show that Corinna has a cross reaction to minor antigens. Her mother's blood type doesn't match, but her father's blood is a perfect match--a 1-in-50 million chance. Nelson must be located in order for Corinna to survive. Carter's shift is over, so Greene takes the case. But Carter can't stop thinking about Corinna and searches all over Chicago for Nelson.

   Meanwhile, Lucy also tries to locate Nelson after her shift ends. Corinna's condition worsens, and Benton needs to operate or else she will die. Benton performs surgery without the blood. Lucy and Carter team up and search all over Chicago, encountering dangerous situations including Carter's possible exposure to TB (tuberculosis). They eventually locate Nelson directly across the street from the hospital at Doc Magoo's, the local diner. Corinna finally gets her life-saving transfusion. The total team effort of the emergency room staff of Chicago's County General Hospital might save Corinna's life
   

9. Good Luck, Ruth Johnson

   Greene continues to stay at Hathaway's house. Ross queries Greene about his date with the new Chief of Emergency Services, Amanda Lee. Hathaway handles a case involving an 8-year-old boy, Wilson (JESSE JAMES). Wilson sustains minor injuries when hit by a car while riding his bicycle with his 8-year-old friend, who was shot to death. Wilson claims a man chased them. But later Hathaway discovers bullets in Wilson's belongings, and he confesses to shooting his friend, who refused to give Wilson his boots. Wilson displays no remorse.

   Since today is the hospital's 100th anniversary, Lee arranges for Carter to escort a woman, Ruth Johnson (ANNE PITONIAK), who was born 100 years ago today. Carter gives a tour to Ruth and over 20 members of her family, including a very pregnant great-granddaughter. After the party, the great-granddaughter delivers a baby and names the girl after her nana, Ruth Johnson.

   Corday answers questions concerning the magnesium overdose. She blames the system for the accident because she had been working for 36 hours straight. Since the patient survives with no bad aftereffects, Corday is cleared of any wrongdoing and the system remains intact. However, her relationship with Benton ends.

   Benton observes a cochlear implant operation (the procedure Benton is considering for Reese) that Dr. Kotlowitz performs on a 3-year-old boy. Kotlowitz schedules the same surgery for Reese. Later, Benton reconsiders and cancels the surgery. Lee encourages Greene to supervise a study on a new pain medicine, and he agrees
   

10. The Miracle Worker

    Corday treats David Gardner (TOM AMANDES), an attractive 44-year-old symphony trumpet soloist concerned that the surgery needed to remove his prostate cancer will make him sexually dysfunctional. She adeptly calms his fears. Aware of their mutual attraction, the two share supper at Doc Magoo's.

    Paramedics transport an 18-year-old flatlined boy. After Carter successfully resuscitates him, the teen's heart beats, but he's brain dead. Later, a 16-year-old girl with liver failure, who desperately needs a transplant, enters the emergency room. Her type AB blood matches only two percent of the population--but it is the same blood type as the brain-dead boy. Carter gets his Christmas miracle when the boy's mother, Mrs. Richards (LAURIE O'BRIEN), agrees to donate her son's liver to the girl.

    Benton cannot have dinner at his sister's house because Romano, as usual, gives his own work to Benton to complete. After Romano leaves, one of his patients, Mr. DeMisa (TRAVIS McKENNA), requires emergency surgery, but Romano doesn't respond to his page. Benton begins surgery, and Romano finally arrives--drunk. When Benton won't let him operate, Romano threatens to terminate Benton's residency. Fortunately, Benton proves Romano's intoxication with a blood test. After a hectic day, Benton cheers up when Carla brings Reese to the hospital to see him.

    Greene receives an application from NASA to become an astronaut. He discovers that a fellow medical school alumnus is part of an upcoming mission and recommended Greene for the team. Carter's exposure test to TB (tuberculosis) proves positive, and he must take medication for six months. Lucy agrees to go on a date with Dale, who confides to Carter that he hopes to have sex with her.

    A woman (SARA MORNELL) about to give birth is rushed to the hospital by her husband (SCOTT MOSENSON), who crashes into another auto en route. The driver of the other car is also transported to County General and dies. The husband gets arrested because his blood alcohol level is above the legal limit, and he misses the birth of his child.

    Benton successfully performs an appendectomy on Dr. Parks' 8-year-old granddaughter, Gwen (TARA KLEIGER). A day-care worker suggests to Benton that Reese requires a "special needs" environment because he's exhibiting problem behavior.

    Ross jeopardizes a liquid pain medicine study by surreptitiously giving some of the drug to Joi's son, Ricky. Greene discovers the secret and informs Weaver. They decide not to tell Anspaugh because, by violating protocol on a federally funded trial, the hospital would be unable to obtain research money and Medicare payments for years. Ross is upset that Hathaway believes he made a mistake. But Hathaway helps an end-stage cancer patient who needs to smoke marijuana in order to get relief from his pain. Hathaway also clashes with Evans, who obtained a grant for a seminar at the clinic without consulting her.

    Lucy begins her surgical rotation under Benton and Corday. Romano offers to get Corday's fellowship reinstated and asks her to assist him in surgery. Weaver interrogates Corday, asking if Romano ever sexually harassed her. Corday denies it and concludes that Doyle must have filed charges. Doyle explains to her that it's a matter of self-respect. Later, Corday admits to Weaver she might be of some assistance in the investigation.

    Greene makes sure Pickman (recurring guest star EMILY WAGNER) isn't reprimanded for a mistake she made while working under a new paramedic policy.
