ER, Season 12

Second-year residents Abby Lockhart, Neela Rasgotra, and Ray Barnett have now become the teachers. And Dr. Archie Morris (Scott Grimes) realizes he makes a better manager than a doctor. Dr. Pratt resolves issues with his family through his estranged father (Danny Glover), while a new attending doctor (John Leguizamo) poses as a patient to test the knowledge of the ER staff, causing friction with Dr. Kovac that leaves Abby caught in the middle. But this new doctor has a few disturbing secrets of his own. John Stamos first appears as paramedic Tony Gates as he and Neela rush to the scene of a horrific plane crash to bravely help as best they can. Meanwhile, Abby and Kovac’s relationship deepens as they prepare for a child in their future. James Woods, Diane Ladd and Armand Assante guest star and Noah Wyle returns in a series of special episodes following his humanitarian work in Africa. It’s a new day in the ER.
