Prime Video is sharing the trailer for the new series Countdown, starring Jensen Ackles as LAPD detective Mark Meachum, who is recruited into a secret task force to investigate the murder of a Department of Homeland Security officer.

The show’s official logline reads, “When an officer with the Department of Homeland Security is murdered in broad daylight, LAPD detective Mark Meachum is recruited to a secret task force, alongside undercover agents from all branches of law enforcement, to investigate. But the hunt for the killer soon uncovers a plot far more sinister than anyone could have imagined, kicking off a race against time to save a city of millions.”

Countdown is created, executive produced and showrun by Derek Haas, and also stars Eric Dane, Jessica Camacho, Violett Beane, Elliot Knight and Uli Latukefu.
