Anthony Dexter---bare-chested most of the film with the smoldering nostrils from "Valentino"---as "Captain Kidd" is saved from hanging by an Earl who wants to get his hand on Kidd's treasure. The Earl thinks the best method is to put a woman confederate (Jeanine Duvall) aboard Kidd's ship as a slave girl to wrest or wrestle the information from him. They fight a lot as a prelude to falling in love, and then work together against the evil Earl's none-too-well laid plan. Alan Hale, Jr. (Simpson) is along as Kidd's trusted friend, while Sonia Sorrell (as Ann Bonney) displays a lot of what the best-undressed female pirate wasn't wearing on pirate ships of the time.
