Jared (Paul Walker) and Sam (Jessica Alba) live a rustic life in the Bahamas. When Jared loses his job and his old college friend Bryce (Scott Caan) comes for a visit, the opportunity to realize his dream arrives. Bryce, a lawyer from New York City, and his girlfriend of the week Amanda (Ashley Scott), acquired the use of a luxury vacation house and boat.
Both couples take a boat trip and do some snorkeling. As they investigate the area, they come across the remains of a crashed plane containing a large quantity of cocaine, and an unidentified shipwreck containing treasure. They decide not to report the crashed plane and its cargo until they have secured their claim on the sunken ship.
