It was the fourth in a series of five films produced by Constantin Films and starring Lee, who was best known at the time for playing the role of Dracula in a long-running series of Hammer Studios horror movies. The Blood of Fu Manchu costars Richard Greene as Fu Manchu's British nemesis Nayland Smith, a Scotland Yard detective.

Plot Summary
In his jungle lair, Fu Manchu (Lee) creates a special poison that causes pain, blindness, and eventual death to its victims. To spread the poison, which only works on men, Fu Manchu kidnaps a group of women and turns them into "carriers" who can administer the poison with a kiss. The women are then hypnotized and sent out around the world to assassinate Fu Manchu's enemies. One of these is Nayland Smith (Greene), who receives a kiss and is blinded by the poison. His assassin is run over by a car and killed, but Smith and his assistant Dr. Petrie (Marion-Crawford) trace the attack to Brazil, and travel there in the hopes of finding a cure. They team up with agent Carl Jansen (George), medical expert Ursula Wagner (Rohm), and self-centered local bandit Sancho Lopez (Palacios) to defeat Fu Manchu's plans and save Smith from death.
