Certainly not one of the pinnacle of Abbott and Costello's career for sure. When it came to them meeting fictional characters, they should have stuck to monsters. This pirate spoof does little to skewer the genre. The pirate theme serves only as a new dressing for their old routines.
Bud Abbott plays Rocky Stonebridge and Lou Costello is Puddin' Head, a duo of tavern workers. On the way to work, Lady Jane (Fran Warren) gives them a love letter to give to the tavern singer Bruce Martingale (Bill Shirley, I DREAM OF JEANIE). Dinning at the tavern that evening are notorious pirates Captain Kidd (Charles Laughton, MUTINY ON THE BOUNTY) and Captain Bonney (Hillary Brooke, THE MAN WHO KNEW TOO MUCH) and Puddin' inadvertently switches the letter for a treasure map. Captain Kidd spends the remainder of the film trying to get the map back.
