Joe E. Brown is a sailor who hopes to match the accomplishments of his seaman father. Unfortunately, Joe is perhaps the clumsiest gob ever to sail the seven seas. Nor can he steer clear of trouble: Through a series of wholly unbelievable circumstances, Joe finds himself alone on deck of a ship that's about to be shelled for target practice. He redeems himself for this and all past misdeeds when he inadvertently breaks up an espionage ring. Son of a Sailor is typical Joe E. Brown fare, but it's the sort of surefire material the public craved; indeed, at least one theatre manager insisted that Warner Bros. (Brown's home studio) send him more of the same.
