Robert Wallace travels to Hong Kong to bust a gang of drug trafficker's. There he finds help from Tang and Suzy, as well as his fellow Supermen Max & Jerry.
An American agent (an unusual character considering this is a dubbed movie full of Italian and Chinese actors) goes to Hong Kong to rescue some narcotics agents who have been kidnapped by drug traffickers. He teams up with two Kung-Fu-fighting international thieves (one is mute and does wacky things in the tradition of Harpo Marx), a Kung Fu instructor, and a female Kung Fu expert.
