The most evil man in the world Fu Manchu (Christopher Lee) has kidnapped the daughters of top scientists, in this second film in the Fu Manchu series, to force their fathers to aid him in his diabolical plot to conquer the world. Though when he has no more use for one of these daughters into the snake pit she goes...
Inspector Nayland Smith (Douglas Wilmer) is of course trying to foil Fu Manchu who now possesses a death ray that can destroy targets across the world. The first test is successful, destroying an ocean liner but can Fu Manchu be stopped before he destroys St Pauls cathedral and kills the world's elite assembled for a conference in London?
Amid much pseudo-Oriental nonsense and antics across the world we'll find out if Fu Manchu succeeds or not. The film is enjoyable though plot wise is a bit of a mess and the sexploitation angle is heavily played up having young women in revealing outfits being menaced and tortured, the latter often by Manchu's daughter Lin Tang (Tsai Chin) who was always a highlight of the Fu Manchu series along with Christopher Lee of course.
