After returning home from Iraq, former Marine John Triton (Cena) and his wife Kate (Carlson) decide to take a vacation. Meanwhile, criminal mastermind Rome (Robert Patrick) robs a jewelry store with his accomplices: his attractive girlfriend Angela (Abigail Bianca), Morgan (Parker), Vescera (Gibson), and Bennett (Bennett). While running from the cops, they stop at a gas station, where John and Kate have stopped as well. When a patrol car arrives to fill up, Morgan shoots one and Rome injures the other. After Bennett knocks John out with a fire extinguisher, Kate is kidnapped. Morgan shoots at the gas tanks, causing the store to blow up with John inside. John survives, emerging to take the abandoned patrol car. He gives chase, with every single member of the gang shooting at him. They go through a construction area, and to the edge of a lake. Under heavy fire, John falls out the car and into the lake.



The criminals decide to travel through the swamps to avoid the police, still with Kate as their hostage. John revives and, despite an officer's lack of permission, pursues them. After an altercation between Morgan and Vescera to show how crazy Morgan is, Rome decides that they have no further use for Vescera and shoots him, leaving the body for the alligators. Kate gets into heated arguments with the group, Angela especially, who strikes Kate whenever she insults her or tries to escape.



The criminals eventually arrive at a shack and rest there for the time being. Triton gets delayed when some fugitives attack him. He subdues them both and tracks the gang to the lodge. He arrives and kills Morgan, who was sent out to turn on the electricity, with a knife that Vescera dropped when he was killed. He then kills Bennett when he goes out to check on Morgan, beating him down and stomping on his neck. As he drags the bodies under the shack, the police officer he met earlier "grants" him further permission to do what he must and turns off the electricity for a distraction.
