Marooned chronicles a castaway's increasingly desperate attempts to return home to warn his family of the impending arrival of the Black Freighter, a phantom pirate ship which houses the souls of the damned. To escape the deserted island he uses the gas-bloated bodies of his former crewmates to float a raft, fending off sharks en route; to infiltrate the (supposedly) pirate-controlled Davidstown, he murders a trusting couple and returns dressed in the man's clothing; to save his family he attacks a night watchman who is patrolling the house. However, this watchman is actually his wife, and he soon realizes that there has been no attack and his efforts have only brought about his own destruction. The man returns to the beach to see the Black Freighter approaching, ready to claim the only life it truly desired - his. He boards eagerly.
