NBC Description

KELLIE MARTIN JOINS CAST IN FIFTH SEASON PREMIERE: It's a difficult first day at County General for Lucy Knight (Kellie Martin, 'Christy,' 'Life Goes On'), a by-the-book, third-year medical student whose stellar technical knowledge of medicine only serves to distance her from the human realities of her chosen field.

Even before Knight shows up for her first day, she is confronted by a roadside injury that leaves her frozen with doubt while her first assignment with Dr. Carter (Noah Wyle) creates an immediate tension between the two.

During her first tour of duty, she encounters a hula group whose lead dancer got a little too close to the flame and a fireman whose tragic accident threatens to take him away from his loving family. Her only respite comes from Nurse Hathaway (Julianna Margulies), who takes Knight under her protective wing.

Meanwhile, Dr. Greene (Anthony Edwards) and Dr. Weaver (Laura Innes) try to provide on-the-run guidance for Knight while Dr. Benton (Eriq La Salle) and Dr. Corday (Alex Kingston) unwittingly shock the young student.

Dr. Ross (George Clooney) discovers that Knight has a knack for diagnosing his pediatric patients and invites her to observe several cases. Gloria Reuben also stars. Ken Kercheval ('Dallas') guest-stars.

Short summary

Third-year med student Lucy Knight reports to the ER for the first day of her rotation. Greene takes a paternal interest in her, helping her get acquainted, but she gets off to a bad start with the irritable Carter. The rest of the day finds her informing a wife of her husband's terminal condition, comforting a pregnant woman, getting locked on the roof and trying to figure out Weaver's "Tour on Tape."
