Crossing Hennessy - Jacky Cheung (2010) - Pik Uk Prison, Sai Kung

Oi Lin's boyfriend is Xu (Andy On) and has a bit of a temper, hence why he is locked away and also why they are going out - he came to her aid when she was assaulted on a bus one day. Anyway, he is incarcerated in Pik Uk prison until his release later in the film. Incidentally, Andy On and Tang Wei would be filming together again a few years later for Blackhat.
