A group of young divers are treasure hunting in the shark-infested waters of the Bahamas. During one of their dives, they locate the wreckage of a cargo plane on the oceans floor. Believing their dream of finding sunken treasure has come true, they get more than they bargained for when they discover the plane contains millions of dollars in illegal drugs. But as they argue among themselves about what to do with their prize, the friends soon realize theyre not the only ones interested in the narcotics. Dangerous criminals are also searching for the drugs, and now the treasure hunters themselves have become the hunted.
