When a former actor moves into an apartment building with the intention of commiting suicide, he is saved by a Taoist priest who used to specialize in hunting Chinese hopping vampires: or Jiāngshī. Elsewhere in the building, a woman turns to a specialist in black magic to bring her husband back to life.

Jackie Chan stars as Asian Hawk, an Indiana Jones-style adventurer looking to make a fortune in exotic antiquities. After Hawk discovers a mysterious sword in Africa, a band of Satan-worshipping monks kidnap his ex-girlfriend Lorelei, demanding the sword as ransom as well as other pieces of the legendary Armour of God — a magical outfit dating back to the Crusades.
