In a construction site under the full moon, construction workers dig too deep and inadvertently wake up Joe (Alex Lam), a vampire that has been lying underground for a century. Dazzled by the vibrancy of a modern city at night, Joe wanders around and runs into Apple (J. Arie), a jilted girl planning to kill herself. Eager for a taste of blood, Joe follows her home and helps her and her grandmother get rid of thugs sent by a real estate developer who wish to buy them off. What started as a battle for property turns out to be a battle among vampires.

Four loser gangsters devise a scheme that is eviously ingenious (or profoundly stupid): to disguise a minibus as a police vehicle to rob cross-border rucks that carry human carcasses with money inside. The ploy kicks into action one evening in the New Territories, and the plot thickens with spooky and deadly encounters, including one with an identical police car – also a fake, but manned by killer gangsters who are after the same dead bodies.
