Cross Harbour Tunnel.

Wong's no-budget indie (dreamt up in a night, shot in a week) tells four distinct stories which intersect in the manner of Mystery Train. They range from character-based comedy (a young couple nervously venture into a 'love hotel' for the first time) to Grand Guignol melodrama (a Filipina maid seeks revenge on her two-timing lover - the actress being the director's mother's real-life maid).
