Checkmate (1973) by Lem Amero
aka: Pepper-Girl, die Superagentin
This film definitely is a rarity, – at least concerning its degree of popularity. Equally famous actress Diana Wilson aka Pepper Burns, brutally dubbed [in the german version] saves the world from four atomic time bombs, downcounting thanks to Mme Chang (An Tsan Hu), japanese blackmailer, who seduces and terrifies her enemies with clever chess manoeuvers and a very well equipped female killer commando.
