The Pig (Harold Sakata) is an international crime lord who has commissioned the creation of a lethal "freeze bomb," which he plans on auctioning off to the highest bidder. Dr. Mason (T.E. Forman) is appalled; he intended his climate control device to be used to eliminate droughts. He sabotages the operation, destroying his files and condensing all the data into a microdot which he implants in the forehead of his assistant, Felicia (Terry Moore). When Mason turns up dead and Felicia is kidnapped, it's up to karate-kicking detective John Ash (Jim Kelly) to investigate. With his partner, Li (Myron Bruce Lee), Ash infiltrates the Pig's cathouse hideout and finds the girl, though the sadistic villain has already cut the microdot out of her skin and escaped to the mountains via ski lift. While Li cleans up some police corruption they've discovered in the Pig's organization, Ash pursues his quarry until he can exact justice with lethal martial artistry and an airplane crash.
