When a police officer shot during a robbery is rushed to the emergency room, Lewis, Neela and Ray stabilize him, but the injuries to his carotid artery, which supplies blood to the brain, leave him in a coma. The stricken officer's 15-year-old son must decide whether to authorize a risky operation that may save his father's life or to leave him permanently comatose. Abby tries to convince a girl with appendicitis to have surgery at County General, but her father wants her transferred to another hospital because his father died during an operation at County.
On Christmas Eve, the emergency room staff scrambles to finish work and go home for the holiday. While Abby treats a dialysis patient who is in critical condition, she can't reach his personal physician because he doesn't want to be disturbed during the holidays. Meanwhile, after much effort, a distraught Chen finally finds someone to work her shift so she can take care of her ailing father. Concerned for her, Pratt stops by her house and finds her struggling with her father's worsening health. Carter and Wendall (recurring guest star MÄDCHEN AMICK) grow closer and share an awkward kiss as they wish each other a merry Christmas.
Recently promoted to Chief of Emergency Medicine, Lewis finds out how hard it is to be in charge of her colleagues. Patient satisfaction scores are down from the previous years, and it's primarily because the residents are not spending enough time listening to the patients--especially Neela, which surprises Kovac. When Lewis confronts Abby about instances when Abby has circumvented accepted procedure to help patients, Abby angrily goes outside for a break. An SUV zooms in and a frantic boy, Little C (KENDRE BERRY), begs her to look at his wounded older brother, CJ (EDWIN MORROW). But when Abby bends to look into the car, she is pushed in and abducted by the gang members, with no witnesses.
In an effort to raise plummeting patient satisfaction scores, Lewis directs Kovac to teach the residents effective patient communication. Two teenagers are brought to the emergency room with gunshot wounds. Kovac, Neela and Sam treat one victim while Lewis, Pratt and Ray attend to another. When one of the patients dies, Neela does a poor job of informing the grandmother--who becomes hysterical. A personal injury attorney sets up a mobile office outside the emergency room, infuriating Lewis as the lawyer attempts to turn dissatisfied patients into clients. Abby returns to the ER even though she is still experiencing the trauma of her recent abduction.
When a 16-year-old girl who had received a kidney transplant from her father arrives at the emergency room feeling dizzy, Carter traces the problem to a new drug that the girl was taking to control seizures related to her kidney dysfunction. Her father feels guilty because he pushed for her to take the new drug, and its side effects may force his daughter to go back on dialysis. The doctor who prescribed the medication, Dr. George Henry (CHAD LOWE - "Life Goes On"), is Carter's former student. Carter asks Neela to post information about the drug's side effects on the Internet, which causes an uproar when the pharmaceutical company finds out. After Abby and Neela complain about their lackluster dating lives, they are assigned to work with Jake (recurring guest star EION BAILEY - "Almost Famous," "Band of Brothers") and Kovac--men they each find attractive.

Kovac and Pratt examine a man who was shot when he confronted his boss with a gun. Jake (recurring guest star EION BAILEY) tries to convince Abby to date him despite his being a student.
Weaver encounters an evasive patient, Helen Kingsley (FRANCES FISHER - "Titanic," "House of Sand and Fog"), who shocks her by revealing that she is her birth mother, who at the age of 15 delivered Weaver and put her up for adoption. As they share life stories, their budding relationship withers when Weaver confesses to the evangelical Christian that she's a lesbian. Meanwhile, Pratt warily assigns Jane (recurring guest star SARA GILBERT - "Roseanne") to attend to a confused elderly woman, while Carter causes a commotion when he confronts a scheming couple hoping to get some painkilling drugs.
When Ellie Shore (CYNTHIA NIXON - "Sex and the City"), a young mother of three, is brought in with symptoms of a potentially fatal stroke, Kovac and Sam fight the odds to save her life. Knowing that a controversial surgical procedure is his wife's only chance at a full recovery, Ellie's husband must make the unenviable decision to risk her life in order to save it. Meanwhile, Neela and Ray discover a dark secret when three ostensibly neglected children show up in the emergency room. And Carter is in the midst of a love triangle when Wendall's (recurring guest star MÄDCHEN AMICK) professions of love force him to either cut ties to his ex-girlfriend in Africa or lose Wendall.
In Iraq, a young girl is wounded in a car bombing, and local hospitals are not equipped to help. Michael Gallant (former series star SHARIF ATKINS), who is stationed in Iraq, enlists Neela's support to secure the necessary treatment at County General, but getting the girl to the United States proves to be extremely difficult. With time running out, Gallant resorts to calling in a favor to bring the young girl to Chicago. Meanwhile, Neela is redefining her role at the hospital and rediscovering her romantic feelings for Gallant.
Neela is surprised when she hears that Gallant (former series star SHARIF ATKINS) came to the emergency room with a young Iraqi burn victim. Sam is troubled by a visit from her ex-husband. Pratt treats a child whose gun discharged, and the doctor learns that the boy received the weapon from an unusual source.
The staff treats a woman suffering from the effects of a hunger strike, but the patient refuses to accept food or help until she has proof that the INS (U.S. Immigration and Naturalization Service) will grant her son's deportation case a new hearing. Neela, Sam and Lewis are unable to treat her as long as she and her lawyer refuse aid--which goes against all of their training. Meanwhile, Abby suspects that a 72-year-old woman, Birdy Chaddock (Academy Award winner LOUISE FLETCHER - "One Flew Over the Cuckoo's Nest," "Star Trek: Deep Space Nine"), is a victim of elder abuse but is unable to prove it.
Eighty-five-year-old Jules "Ruby" Rubadoux (recurring guest star Academy Award winner RED BUTTONS - "Sayonara," "The Poseidon Adventure") is wheeled into the emergency room and erroneously accuses Carter of killing Ruby's wife 10 years ago. Although Abby believes Ruby is too old to undergo surgery to correct a heart murmur, the attending doctors opt to perform the operation. Meanwhile, Pratt treats a domestic violence victim and makes a date with the social worker assigned to the case. As Pratt arrives for the date, he realizes he has gotten himself into more than he bargained for. Former series star PAUL McCRANE directed the episode.
Much to everyone's chagrin, Dr. Archie Morris (recurring guest star SCOTT GRIMES - "Band of Brothers") is appointed as the new chief resident and immediately challenges Pratt as they treat casualties from an apartment building fire. Frustrated at not achieving tenure, Lewis is short-tempered with Carter. Weaver tries to pacify Lewis but only makes things worse. Ray heeds the advice of several doctors at the hospital and discharges a teenaged sickle-cell anemia patient.
Pratt loudly reprimands Neela for performing a complicated procedure on a baby; Abby misdiagnoses a patient; and Ray's procedural misstep on a victim who was stabbed produces terrible results. Meanwhile, Carter travels to Paris after learning that Kem's (recurring guest star THANDIE NEWTON - "Mission: Impossible 2") mother has been hospitalized. Once there, Carter makes some life-altering decisions.
On Carter's final shift at County General, four new interns begin their medical careers. After completing their rounds, Carter, Kovac and most of the emergency room staff attend Carter's surprise going-away party. Ray leaves to go to another event where the revelry is interrupted by a disaster that truly tests his triage abilities. The casualties are taken immediately to the hospital where a skeleton staff, headed by Abby and Neela, must overcome their lack of experience and treat the patients. Meanwhile, Pratt finally gets the courage to confront his father, Charlie (recurring guest star DANNY GLOVER - "Lethal Weapon" films, "The Royal Tenenbaums"). And Sam and Kovac search for Sam's son after he runs away in search of his imprisoned father.
For the overburdened doctors and emergency room personnel of County General Hospital, an urban Chicago teaching hospital, the difference between life and death often depends on split-second decisions.

But the chaos, stench and hazards of the country's long civil war threaten to curtail his efforts, and Carter is placed in immediate danger. Meanwhile, still in the strife-torn country, Kovac is seen in flashbacks as he battles debilitating malaria while he ministers to the sick and dying.
A frustrating day for Abby gets even worse when she receives an upsetting letter from Carter, who is still in the Congo. Her fellow nurses protest work conditions, and her opinions are ignored.

Confident second-year resident Pratt wants to prove his abilities when he works the graveyard shift (11 p.m. to 7 a.m.), but his heroics sometimes backfire. Pratt shows contempt for a man, Ed Gamble (PAUL CASSELL), who presents no symptoms of disease but temporarily loses his speech. As Weaver decries the "incompetence" of her staff, she also makes a grievous error. A screaming man with a broken leg waits several hours for treatment, and Neela deals with a little girl who arrives with her beloved grandmother whose status is DNR ("do not resuscitate"). Meanwhile, Abby is desperate for money and credit. Later, she meets both Kovac and his new girlfriend. And Corday begins to appreciate Dr. Dorset (recurring guest star BRUNO CAMPOS).

A distracted Kovac also runs afoul of a psychiatrist who overmedicates an abused foster child who wants to go back to his drug-addled mother. Meanwhile, Lewis enjoys the company of sarcastic patient Ben Hollander (recurring guest star, Emmy Award winner BOB NEWHART - "Newhart"), who once threatened suicide over his impending blindness. A chatty, upbeat pharmaceutical representative, Terra (SARAH SHAHI), peddles her wares. A man turns violent over an exorbitant hospital bill. And Dr. Nick "Coop" Cooper, a second-year resident, makes romantic advances towards Chen.
To everyone's amazement, Lewis makes a date to share a home-cooked dinner with the elderly Ben Hollander (recurring guest star, Emmy Award winner BOB NEWHART - "Newhart"), her depressed patient who is going blind.

Nearby, Lewis is unaware that her ex-husband, Chuck (recurring guest star DONAL LOGUE), is involved in the flaming disaster.

And Pratt notices the beautiful Valerie (recurring guest star JOY BRYANT), who is visiting her nervous brother Gallant.
On Christmas Eve, the chilly emergency room staffers do their best to observe the holiday while a crusading Carter does the same--half a world away in a rundown Congolese medical clinic. Flashbacks reveal his relationship with Makemba "Kem" Likasu (recurring guest star THANDIE NEWTON - "Mission: Impossible 2"), a beautiful African AIDS worker, as their clashes over meager resources slowly give way to a deep love affair. As Carter adjusts to the heat, filth and dangers of the region, he keeps in touch with his Chicago friends and embarks on a personal mission to help a pregnant mother who is dying of AIDS.

In a special episode focusing on the neonatal intensive care unit (NICU), medical students Abby and Neela serve a three-week rotation in the unit and gain a new perspective on emergency care.

Meanwhile, Abby and Neela cope with the driven director of neonatology, Dr. Meagan Raab (L. SCOTT CALDWELL), and a humorless veteran NICU nurse, Virgie (JOANNE BARON). And Abby is surprised to find Weaver in the NICU, accompanying her lover, Sandy Lopez (recurring guest star LISA VIDAL), who gives birth to their son. Although she was initially intimidated by Neela's ease in this setting, by the end of her time in NICU, Abby is becoming a confident, skilled doctor. But Neela questions her own fortitude in such an oftentimes tragic place. Series star LAURA INNES directed the episode.
Carter makes the mistake of bringing his naïve girlfriend, Kem (recurring guest star THANDIE NEWTON), to observe the emergency room. Kem makes an impact--wanted or not--almost everywhere she wanders, ranging from an AIDS ward to the classroom and even in an unsanctioned ride with the paramedics.
