In 16th Century China, Ming guard Fong Sau-ching relentlessly tracks the ruthless villain Feng San, who is notorious for raping and killing women. Feng San murders the princess and the emperor is furious that Fong Sau-ching wasn't able to save her. He gives Fong one last chance to capture Feng San within 20 days. After Feng San steals the priceless and magical Black Jade Buddha, a magical artifact that grants user the ability to time travel; Fong and Feng San are transported to 300 years in the future. 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. 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. Meanwhile, Feng San is still out and about and he's now a thief working for the local crime boss. He kills his boss after he was caught trying to rape his boss' girlfriend and a fight started. He then kills her in a brutal fashion of breaking her limbs. Later, Fong finds out that this whole time Polly was a prostitute and she's been using him the whole time, so he vows to not be her slave any longer. Around the same time, Fong reads a newspaper about a woman who's been murdered and her limbs are broken. He is instantly reminded of how Feng San kills his victims and now knows he's still alive. Feng San kidnaps Polly by pretending to be one of her clients. Fong goes to rescue her and is forced to admit that he loves Polly when Feng San has held her hostage. A big fight between Fong and Feng San ensues with Feng San being the victor and Fong severely injured but is able to recover after making it to the hospital. 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. He steals a load of firearms from the local arms dealer and plans to take the modern firearms back to the 16th century and conquer the dynasty. Fong is also aware of the Buddha's Wheel and predicts that Feng San will be there. He then trains for the upcoming battle and crafts a sword to combat Feng San. After finishing the sword he leaves Polly without her noticing because he doesn't want her to get involved. 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. On the roof top, Fong confronts Feng San and tells him that no matter what happens he will fulfill his duty to the emperor and take Feng San back to pay for his crimes. Fong eventually kills Feng San by impaling him on shards of broken glass. He takes Feng San's body and activates the Buddha's wheel. Polly arrives at the scene but was too late. She watches tearfully as Fong leaves. Some time later, Polly quits being a prostitute and is now working at a corner store. As she went to take out the trash, she runs into a man who resembles Fong.
