Two Years Before the Mast.

In 1834, Charles Stewart (Alan Ladd), the spoiled, dissolute son of a shipping magnate, is shanghaied aboard the Pilgrim, one of his father's own ships. He embarks upon a long, hellish sea voyage under the tyrannical rule of Captain Francis Thompson (Howard Da Silva), assisted by his first mate, Amazeen (William Bendix). One of his crewmates is Richard Henry Dana Jr. (Brian Donlevy).
