"Things take a decidedly weird turn in The Blood of Fu Manchu, the fourth entry in the five-film cycle reviving Sax Rohmer's Chinese super-villain, Fu Manchu, from maverick British producer and writer Harry Alan Towers (Circus of Fear). Directed by the prolific Spaniard Jesus Franco (The Awful Dr. Orloff, Oasis of the Zombies), The Blood of Fu Manchu sees the Oriental overlord operating from a laboratory deep within the South American jungle. With the help of his sadistic daughter Lin Tang (Tsai Chin, The Virgin Soldiers), Fu Manchu connives to create a deadly pandemic by deploying ten beautiful women whose lips are laced with killer venom... Nayland Smith (Richard Greene, The Adventures of Robin Hood) becomes infected, but his ever-loyal Man Friday Dr Petrie (Howard Marion-Crawford, Gideon's Day) leads the international efforts to find an antidote and bring down Fu Manchu."
