Mummy Dearest

Lee Kam Lun is an intelligent but psychologically unstable young man who is very filial and loves his mum dearly. Trouble brews when he accidentally killed a junkie one night. His subsequent actions arouse the suspicion of another intelligent Inspector, who kick start a game of cat and mouse by befriending Lee’s mum as he tries to expose Lee as the killer. Director Ronny Yu gives us an effective and tight psychological thriller with some dark humor and plot twists in one of his earlier directorial effort.
