Scarlett (Charlotte Kirk) is a low-level thief who, while working as a pickpocket in a nightclub, falls for the suave Rob (Philip Winchester). Rob, it turns out, is a diamond smuggler working with Danny (Sean Pertwee) and Baraka (Hoji Fortuna), selling a massive diamond to queen-fence Charlie (Stephanie Beacham). Following Rob's death in the desert at the hands of his fellow smugglers, Scarlett becomes known as "Duchess," intent on a bloody revenge.
