Plot synopsis

Medical student Lucy Knight (Kellie Martin) begins her studies in the ER. As she spends time learning the layout and staff of the ER, we learn of Dr. Anna Del Amico's departure.

Carter is reminded of himself as he watches Knight learn and practice. The two have a large number of conflicts before they find a way to work together.

Elizabeth Corday begins her surgical internship all over again in order to keep her job at the hospital and ends her relationship with fellow surgeon Peter Benton. Benton finds out that his son is hearing impaired, and he considers a cochlear implant. Eventually, he decides against it.

Weaver opts for a full-time chief of emergency medicine post, but the post goes to an East Coast doctor, Amanda Lee. Dr. Lee soon develops a more-than-professional interest in Mark Greene with Lee later revealing to be a fraudulent psychopath who later leaves under cloudy circumstances.

Greene does a paramedic ride-along and Doug Ross has at last settled down with Carol Hathaway.

While on probation after performing a risky procedure during the fourth season, Ross breaks protocol again by informing a mother how to alter the medication given to her disabled son with ALD. She uses this information to kill her son, leaving Ross under fire. He resigns from County and moves to Seattle.
