The Private Eye Blues(1994)

Private investigator Jacky Cheung is adrift. He has separated from his wife (Kathy Chow) and misses his young daughter. His next assignment seems fairly simple: he must track down a troublesome teenage girl (Mavis Fan) and return her home to China. Powerful behind the scenes forces soon become apparent, however, and plunge our intrepid hero into greater trouble than he's ever known.
