Five hundred feet beneath the ocean's surface, the U.S. ballistic missile submarine Colorado receives its orders. Over a radio channel, designed only to be used if the United States has been wiped out, the sub's crew is told to fire nuclear weapons at Pakistan. Capt. Marcus Chaplin (Andre Braugher) demands confirmation of the orders, only to be unceremoniously relieved of duty by the White House. XO Sam Kendal (Scott Speedman) finds himself suddenly in charge of the submarine and facing the same difficult decision. When he also refuses to fire without confirmation of the orders, the Colorado is targeted, fired upon, and hit. The submarine and its crew find themselves crippled on the ocean floor, declared rogue enemies of their own country. Now, with nowhere left to turn, Chaplin and Kendal take the sub on the run and bring the men and women of the Colorado to an exotic island. Here they will find refuge and romance as well as a chance at a new life, even as they try to clear their names and get home.
