Countdown reunites Jensen Ackles with Prime Video, the streaming home of The Boys, where he memorably played the volatile Soldier Boy — this time trading a supervillain-adjacent role for a wisecracking LAPD officer pulled into a secret government task force.
The series comes from creator Derek Haas, a veteran of Dick Wolf's One Chicago and FBI universes, and unspools across thirteen episodes that deliberately escalate from a single daylight killing into a sprawling, city-threatening conspiracy.
Beyond starring, Ackles also serves as an executive producer on the show, which leaned into extensive Los Angeles location shooting and practical stunt work to give the streaming thriller the scope and energy of a feature film.
Countdown is a propulsive action-thriller series created by Derek Haas, a veteran writer of network procedurals including the One Chicago and FBI franchises. Built for streaming momentum on Prime Video, the show trades on the ticking-clock urgency of its title while spinning out a sprawling conspiracy that keeps escalating across its thirteen-episode first season.
Jensen Ackles stars as Mark Meachum, a wisecracking LAPD officer who is recruited into a covert, multi-agency task force after a Department of Homeland Security agent is gunned down in broad daylight. What begins as a single shocking murder investigation soon reveals a far larger and more dangerous plot against the city, forcing the secretive team of operatives to race against time. Jessica Camacho, Eric Dane, Uli Latukefu, and Violett Beane co-star.
The series marks a high-profile reunion between Ackles and Prime Video following his fan-favorite run on The Boys, and it leans into large-scale Los Angeles location work and heavy stunt action to give the show a theatrical scale. Case-driven and fast-moving, Countdown was designed to hook binge viewers and deliver escalating stakes week over week.
