Fan-favorite drama series "9-1-1," "Doctor Odyssey" and "Grey's Anatomy" return to the iconic Thursday night lineup on March 6. From executive producer Ryan Murphy and starring Joshua Jackson and Don Johnson, highly anticipated new drama "Doctor Odyssey" premiered last fall, alongside the No. 1 drama in Adults 18-49, "9-1-1," and the longest-running primetime medical drama in television history, "Grey's Anatomy." All three powerhouse dramas are set to return with all-new episodes Thursday, March 6 on ABC. Be sure to watch the livestream and full episodes right here on ABC.com and stream next day on Hulu.

9-1-1: Ryan Murphy, Brad Falchuk and Tim Minear reimagine the procedural drama with "9-1-1." The series explores the high-pressure experiences of first responders — including police officers, firefighters and dispatchers — who are thrust into the most frightening, shocking and heart-stopping conditions. These emergency responders must try to balance saving those who are at their most vulnerable with solving the problems in their own lives. The show draws from the real lives of first responders who regularly face situations that are often unpredictable, intense and uplifting at the same time.
