Christopher Lee returns as the diabolical super-villian who along with his sadistic daughter Lin Tang (Tsai Chin of THE BRIDES OF FU MANCHU and THE JOY LUCK CLUB) creates a fiendish new chemical weapon that will turn the seas into a giant block of ice. But when his Archenemy Nayland Smith (Richard Greene of TALES FROM THE CRYPT) tracks the madman's trail of kidnapping, murder and massive global destruction, he himself becomes trapped in Fu's impenetrable lair of cruelty. Can any of the world's top secret agents (including a wild performance by Director Jess Franco) now stop the cold-blooded terror that lives in THE CASTLE OF FU MANCHU?
