Three poor fisherman come across a listless yacht with no visible captain. They board the vessel to find a dead body. After reporting their findings to the Coast Guard, the three gain temporary custody of the boat. The authorities hope to find the owner while the trio uses it for a charter boat. The three drips nearly end up in Davy Jones' locker when the owners of the ship appear. They turn out to be big time drug runners and force the trio at gunpoint to smuggle heroin into Catalina.
