Noah Wyle is back in the ER. Max has released the first trailer for The Pitt, its upcoming medical drama from ER alums John Wells, Wyle and R. Scott Gemmill. It reveals that the series will debut on the streamer in January.

Set to music that resembles a ticking clock, the trailer also confirms that the 15-episode season will follow the action in real-time over the course of a single ER shift with the tagline “15 episodes, 15 hours, 1 shift.” (You can watch the trailer above.)

Per the official logline, The Pitt is a realistic examination of the challenges facing healthcare workers in today’s America as seen through the lens of the frontline heroes working in a modern-day hospital in Pittsburgh.

As Deadline has reported, The Pitt was conceived under a different business framework — a modestly budgeted, broadcast-style drama for streaming. It also used an unusual fixed-fee payment scheme for the supporting cast around Wyle.
