Our Neighbour Detective 1995

Directed by Cha Chuen-Yee

When Cheng Kam-Fu (Lawrence Ng) reports his wife missing to the police, Detective Lau (Anthony Wong) suspects there’s more to the disappearance than meets the eye. While his colleagues remain uninterested, Lau begins round the clock observation on Fu’s shop/flat, paying particular attention to his mistress, Lo (Li Yu).
