It was just a family vacation... until the terrorists came aboard. Jackson Barr, Jr., along with his wife and kids, are enjoying a Caribbean cruise when all hell breaks loose. At port in Jamaica, an explosion rocks the ship, and all passengers are sent to shore on lifeboats, where they are told they'll be reunited with their children. But Jack senses something's not right, and hides on the ship. His wife calls from shore: the kids are not there. Now alone on a ship with terrorists in control, Jack must fight for his life—and his kids' lives—in order to reunite his family and bring down whoever's doing this.
