"Iceman Cometh" starts out as a manhunt by Ming royal guard Yuen Biao after a rapist-killer of thirteen women in the royal palace, including a relative of the emperor. The guard is transported along with the killer to a snow covered area by a Tibetan wheel with time travel properties. After the two are frozen in the snow, a scientific expedition finds them years later and brings their frozen bodies back to modern Hong Kong. The guard and killer are accidentally thawed out, and the guard ends up getting involved with a call girl (Maggie Cheung)
Maggie Cheung steals every scene she is in. Yuen Biao is tops in action scenes with his opponent, the actor who played Panther in "Supercop," but Biao is no match for Maggie. She uses him first as a housekeeper to clean up her messy apartment, then as an enforcer to shake down her clients for additional payoff money. She is the one with most of the problems, from a pimp who threatens to throw acid in her face if she doesn't go out with a client to her later run in with the rapist murderer.
The movie also has some nice technical effects when the Tibetan wheel goes into its time traveling mode at the end of the movie, but the real special effect is Maggie Cheung's acting range. She can project some personality on the screen.
