Released in both silent and sound versions, Isle of Lost Ships stars Jason Robards Sr. as Frank Howard, an accused criminal being transported to prison by no-nonsense cop Jackson (Robert Emmet O'Connor). While sailing towards their destination, prisoner and policeman are swept up in a storm at sea and deposited on an island "decorated" with derelict ships. Having already performed heroically during the storm, Howard further proves his mettle by saving heroine Dorothy Renwick (Virginia Valli) from lecherous privateer Captain Forbes (Noah Beery Sr), killing a marauding shark, and braving the depths of the Sargasso Sea to repair a submarine. Understandably impressed by all this, Jackson changes his mind about following the letter of the law and sets about to prove Howard's innocence. Isle of Lost Ships was later reissued in excerpt form as the Robert Youngson one-reeler An Adventure to Remember.
