The series was created by Jed Mercurio, who also serves as showrunner, writer and executive producer, reuniting him with Madden after Bodyguard.

What it's about

Mbatha-Raw plays Commander Katherine Decker, a US Navy officer. Madden is Webb Preston, the charismatic Secretary of Defense. Their connection leads Decker to suspect that Preston may be at the heart of a dangerous conspiracy.

The trailer opens with a submarine on the verge of wrongly launching a nuclear weapon. From there, Preston and Decker work to protect the crew and uncover a national threat, as she begins to suspect he is hiding something more sinister.
