De slechterik Fu Manchu heeft een machine ontwikkeld waarmee hij de hele wereld kan bevriezen. Gelukkig ontdekt de Britse agent Dr. Nayland Smith het duivelse plan op tijd en zet met behulp van Interpol de tegenaanval in.
Nee, helaas is The Castle of Fu Manchu nog niet beschikbaar op Netflix in Nederland.
