Actually more like a western, thanks to its Brazilian setting and bandit subplot, the fourth outing for Christopher Lee as Sax Rohmer's insidious Oriental is cheaply made horror exotica. Lee's stiff performance doesn't help the daft story, as Fu Manchu endows ten gorgeous girls with the "kiss of death" via an Inca poison deadly only to the male and programmes them to kill any influential power-broker who touches their passionate lips. Goldfinger beauty Shirley Eaton is chief among these black widows in hack director Jess Franco's easy-on-the-eye even easier on the brain horror travesty.

In his remote jungle hideout, the evil Fu Manchu and his sadistic daughter Lin Tang have discovered a deadly venom that affects only men. Using mind control Fu Manchu recruits six women to become carriers of the 'kiss of death' targeting key people of political influence. This will prevent them from interfering with his own ambition to spread his venomous death around the World's major cities in a plan to gain World domination.
