The ER is staffed by two new attending physicians: Dr. Gregory Pratt whose rebel days seem behind him as he matures into a new role, and former Chief Resident Dr. Archie Morris who faces the realisation medicine may be his true calling.
The backbone of the ER are third-year year residents Dr. Abby Lockhart, a former ER nurse turned doctor who must balance a demanding career with a new family; and Dr. Ray Barnett whose rock-doc days are finally behind him; along with feisty nurse Samantha Taggart, a tough single mother attempting to balance her difficult personal issues with her demanding professional life.
Now in surgery, Dr. Neela Rasgotra makes a professional change as she recovers from the death of her husband, and new to the ER is intern Dr. Tony Gates, a paramedic turned doctor who sees rules as made to be broken.
Featured this season as recurring characters are Leland Orser as the ER's highly individual surgical attending, Dr. Lucien Dubenko; JP Manoux as surgical Chief Resident Dr. Damien Crenshaw; and a lively group of new interns and medical students.
Guest stars for the first half of the season include Sally Field as Abby's bipolar mother, John Mahoney as a club owner with an colourful lifestyle, and in a six-episode story arc as a patient who suffers a stroke in the overcrowded ER under Luka's care, actor/director Forest Whitaker.
