Last Resort

Last Resort is a thriller set in the near future when the country is very fractured and revolves around the crew of a U.S. nuclear submarine who become hunted after ignoring an order to shoot nuclear missiles. They escape to a NATO listening outpost where they publicly declare themselves to be the world's smallest nuclear nation with 24 nuclear warheads.

Marcus leads a search for three missing crew members of the Colorado, a search that leads them to Serrat's compound, where they receive an ominous demand. Meanwhile, a clandestine meeting between Kylie and Admiral Shepard confirms that the order to fire came through a back channel.

Even as Marcus and Sam learn that they have been charged with treason against the United States, a greater threat within their own crew is brewing. Meanwhile, an old friend of Sam's, Paul Wells (guest star Jay Hernandez, "Hostel"), pays Christine a visit and tries to ease her fears about her husband.

In an attempt to end the standoff on Sainte Marina, Marcus and Sam enter into tense negotiations with the U.S. Government. Meanwhile, when a critical system fails, Grace must take command of the Colorado on a perilous repair operation.

The crew is hit with an attack by an unknown force unlike anything they've seen before. As confusion and aggression take hold, Marcus and Sam can no longer trust their own senses even as they race to save the sub and defend the island.

As Marcus and Sam hunt for the traitor in their ranks who stole their nuclear launch key, Prosser disobeys orders and starts a small war he can't control. Meanwhile Grace and James must work together to defuse a dangerous situation, while back in D.C. Christine is indicted as Sam's co-conspirator.

Grace is haunted by an event from her past as a food shortage threatens the stability on Sainte Marina. A terrible crime turns islanders against the crew of the Colorado while Sam continues his dangerous game with CIA agent Booth. Back at home Christine and Kylie take their own risks as they attempt to get Christine to the island.

The crew of the Colorado waits for a goodwill visit from their families, a visit that will soon turn into a nightmare as Marcus must consider the unthinkable once again. Meanwhile, the true reason for the nuclear devastation in Pakistan is revealed.

Sam and James depart the island in a daring rescue attempt.  Back on the island of Sainte Marina, a Chinese diplomat arrives to make a deal with Marcus.  With scarcity and a prison problem plaguing him, Marcus finds himself treading down a more treacherous path than he could have imagined.

A typhoon, a mutiny and a Washington coup d'etat will force Marcus and his crew into unlikely alliances. As Sam's grief strains his loyalty to Marcus, will Sainte Marina get the supplies it so desperately needs? How far will Marcus go to ensure the crew's survival and will it cost him his life?

Kylie works with Admiral Shepard to bring down the President, using evidence of what really happened in Pakistan. This affords Marcus the opportunity to surrender the Colorado, if all goes according to plan.

In the exciting series finale, a violent battle for control erupts on the submarine, which leaves the Colorado vulnerable to capture by a third party -- one with an exploitative plan. Can Marcus and Sam take control of the sub before it's too late?
