Bodyguard star, Richard Madden and Loki’s Gugu Mbatha-Raw lead the cast.

The eight-episode series follows a valiant naval officer (Mbatha-Raw) whose newfound connection with the secretary of defense (Madden) leads her to discover he may be at the heart of a dangerous conspiracy.

Gugu Mbatha-Raw (Lift, Surface) stars as Commander Katherine Decker. She serves as second-in-command on the USS Kansas, a nuclear submarine and one of the deadliest weapons on Earth. Richard Madden (Eternals, Citadel) stars as Secretary of Defense Webb Preston. With a technology background that makes him different from most politicians, Webb’s innovation and purpose are seen as a threat in more ways than one.

Mercurio serves as showrunner and writer and will executive produce the series alongside Jimmy Mulville for Hat Trick Mercurio and Wendy Mericle. Michael Cuesta will direct and executive produce the first and second episodes.
