Commander Katherine Decker (Mbatha-Raw) has made a name for herself as second-in-command of the nuclear submarine USS Kansas. She soon finds herself in even murkier waters when she enters the world of politics.
Deckers becomes involved with Webb Preston (Madden), a charismatic, crusading defence secretary whose drive for innovation has Westminster worried. When the two become entangled, Decker discovers there may be more to Preston than meets the eye. Is he at the heart of a conspiracy? Are his enemies right not to trust him?
