It started with an experiment gone wrong. A ship carrying the military's latest weapon in the war on terror ran aground. Now it's loose. Jack Hammond is an ex-Special Forces soldier who has returned from the war. He's looking to take a peaceful island vacation with his family and forget about the horrors in Iraq and Afghanistan. Soon after the Hammonds' arrival on the island, a military ship runs aground. It's carrying the military's latest weapon in the war on terror, bloodthirsty creatures trained to kill terrorists. And now they're loose. Soon bodies begin piling up, and a clandestine military unit arrives on the island to deal with the threat. Jack must battle the creatures and hostile soldiers to get his family off the island before it's too late. Before there's no escape.
