To discover the hidden booty of Captain Kidd (Anthony Dexter), the Earl of Bellomont (James Seay) saves the swashbuckling pirate from the gallows only to send pampered Judith Duvall (Eva Gabor) -- disguised as a slave girl -- to seduce the captain into pillow talk. But when the feisty "slave girl" begins to fall for Kidd, she teams up with the notorious sailor and threatens the villainous Earl's plans for Kidd's buried treasure.
