This comedy, heavy on sight gags, has a bunch of crooks taking advantage of a naive, ex-Navy officer Wagner. Wagner sails a group of vessels from the scrap heap in an effort to impress the boss' daughter. Petty thief Kovacs, who fools Wagner into believing he is a ship builder, plans to
use the ship for a bank heist. Wagner and girl friend Hart are captured, and Wagner is forced to skipper the ship. Gorshin tries to take control of the ship, but Wagner signals the Coast Guard for rescue by using Hart's brassiere as a slingshot. Veteran comedians stand out in their roles, but
others have trouble pulling off the laughs.
