After questioning orders to fire nuclear missiles into Pakistan, Captain Marcus Chaplin (Andre Braugher) and the crew of the nuclear sub USS Colorado are deemed traitors by their own country. Forced to take refuge on an exotic Pacific island, they must fight to clear their names so that they can return home.

After Marcus (Andre Braugher) employs an experimental device to elude U.S. warships, a commando team attack sends Sam (Scott Speedman) and Grace (Daisy Betts) into the jungle to defend the island. Meanwhile, Kylie (Autumn Reeser) looks for the source of the attack on the U.S.S. Colorado.

As Marcus (Andre Braugher) looks to control the Colorado’s restive crew, he agrees to run the blockade in order to gain the release of three sailors who are being held by the island’s corrupt mayor. Meanwhile, Kylie (Autumn Reeser) runs up against an unexpected foe in her search for the truth about the attack.

As Marcus (Andre Braugher) considers letting frightened crewmembers leave the island, he is faced with the government’s clandestine efforts to spark a mutiny. Meanwhile, Sophie (Camille de Pazzis) looks to keep Serrat (Aahr Ngaujah) in the dark about the island’s potential mineral wealth.

As Marcus (Andre Braugher) and Sam (Scott Speedman) negotiate with the Secretary of Defense, Grace (Daisy Betts) leads the Colorado on a risky mission to repair the island’s damaged sonar defenses.

A commando raid that contaminates the island’s drinking water sends Marcus (Andre Braugher) and a skeleton crew out to sea to protect the sub, while Sam (Scott Speedman) struggles with drug-induced hallucinations as he tries to fend off the attack.
