Similar to Highlander the film combines elements of sci-fi and historical fantasy with a contemporary setting and action.

Feng San murders the princess and the emperor is furious that Fong Sau-ching wasn't able to save her.

Upon arrival, a titanic martial arts encounter atop a cliff ensues and is only ended when the two men tumble into a glacier where they are instantly frozen.

Later being thawed out and awaken by scientists, Fong Sau-ching must continue his pursuit of his quarry although to survive in 1980s Kowloon with the confounding discovery of electricity, TV and toilets, he's going to need a little help from femme fatale Polly (Maggie Cheung).

Polly hires Fong to be her servant and bodyguard since she knows of his martial arts expertise and in return she will help him get an ID card.

Fong feels extremely shameful for not being able to capture Feng San and once a royal guard like himself is now a servant to a woman.

Fong goes to rescue her and is forced to admit that he loves Polly when Feng San has held her hostage.

Feng San learns that the Buddha's wheel, the magical device that sent him to the future has been dug up and transported to a Hong Kong exhibit.

At the exhibit, Feng San finds a note on the wheel written by Fong that tells him to come up to the roof for the Black Jade, which he needs to activate the time travel device.
