A peasant girl lays dead by the hand of her well-moneyed lover, Anton, and the only witness is Tessa, who vows to testify against him. But Anton’s mother, ranchero and former pirate Mary Rose (played by special guest star Bo Derek), is determined to save her son from the hangman’s noose – even if it means murder. This time, the one who needs the Queen’s protection is Tessa herself.
