Master Hong Kong director Ringo Lam spins this wild genre-bending flick that is equal parts psychodrama, action thriller, caper movie, and ghost story. The film opens with computer designer Ma (Lau Ching-wan) getting kidnapped in a parking structure. His girlfriend Amy Fu (Amy Kwok) informs the police that though he had been jobless for a while and had a lot of debt, he was basically a good egg. Police detective Pit (Tony Leung Kar-wai) soon discovers Ma beaten, bloodied, and dangling upside down from the ceiling of an old abandoned hotel -- one that has been notoriously haunted since the murder-suicide of the owner and his feckless wife. Ma subsequently starts terrifying Amy by behaving like the famous ghost of the hotel. The police, however, suspect that Ma's possession might be a ruse to shield some larger and more nefarious crime. Due to a creative dispute that Lam had with producer Joe Ma, there are two different endings to this film.
