Police Force - Wang Chung (1973) - Shek Pik Prison, Lantau Island

Through the dead body they have recovered, the police identify a woman who knew the deceased and have been tracking her movements. In this scene, Wong's side kick recounts how she has been seen leaving Shek Pik Prison and we are given some footage of that with Fung Hak-on superimposed onto it as he is the recounting her movements.
