Bullet for Hire - Simon Yam (1991) - Stone Nullah Lane, Wanchai

Han and Shan are sent on their first job together, which (although Shan doesn't know it) is to kidnap the wife and daughter of one of their fellow gangsters. It turns out that boss doesn't like his hitmen to have any attachments outside of their jobs and so the loose ends must be tied up. Shan messes the kidnap up and Han finishes off the mother in a brutally comedic fashion - he shoots her in the head and her body falls back onto a hawker trolley which then rolls down the road. The large building with the red trim is the St James' Settlement building.
