In a Hong Kong hospital, worried doctors scratch their heads about a patient covered with pulsating ulcers, who is diagnosed as suffering from black magic. Another patient has worms crawling under his skin. It's the work of a zombie master named Fang, who hangs out in discos, drinks human milk to survive, and drives a Mercedes-Benz.
He picks up a woman at a bar, takes her to his basement dungeon, and pulls a long spike out of the top of her head with a pair of tongs. The spike enables his zombie spell, so right away she keels over, turns into a hag, and expires.
Fang captures one of the doctor's wives, demanding, "I shall drink your milk every day, understand?" The rest of the movie's dubbed dialogs is just as wild. Using his victim's pubic hair, he creates a potion to make her produce milk. Meantime, the doctors sit around talking about how they don't believe in magic.
Eventually, they set a trap for Fang but it backfires. Only one man is left to confront the magician, as well as an army of zombies that includes some of his friends, who have been "spiked." Much of the film's horror imagery is appalling: One woman becomes pregnant overnight and aborts a monstrous fetus; someone who tries to double-cross Fang starts pulling out clumps of his hair and quickly melts into a fleshy blob.
