Prime Video has added Countdown, a new thriller series about the race to stop a major nuclear terrorist attack, boasting an all-star cast and sounding very much like one for fans of shows like Jack Ryan.
The Boys actor Jensen Ackles stars as maverick LAPD detective Mark Meachum, who is undercover in a prison when he is recruited to join a secret task force by Special Agent Nathan Blythe (Grey’s Anatomy star Eric Dane).
