Fu Manchu’s latest mission is discovery of the tomb of Genghis Khan. Possession of the mask and sword of Genghis would give Fu the leadership of the East. Then he could lead his subjects on to victory in the western world, with ultimate extermination of the white race which he fanatically despises.
Fu (Boris Karloff) has a daughter (Myrna Loy) who’s not so pleasant herself. After pop is through torturing the best looking white men for his own purpose, daughter gets ’em for hers. She has the biggest boudoir couch this side of Peking, and pop doesn’t object.
So that Fu doesn’t get to the late Genghis’ paraphernalia first, Scotland Yard dispatches a museum expedition to the spot. After that it’s a contest over the tomb’s contents. Just as Lewis Stone, as Inspector Nayland Smith of Scotland Yard, is about to be lowered into the cavernous mouths of a troupe of starving crocodiles he manages to escape.
Everybody is handicapped by the story and situations [from the story by Sax Rohmer]. It’s strange how bad such troupers as Stone and Jean Hersholt can look when up against such an assignment as this.
