Twilight of the Warriors: Walled In

“Don't cause trouble in the Walled City.”

Chan Lok-kwun (Raymond Lam Fung) is a refugee from the mainland, a drifter in 1980s Hong Kong who gets by on underground fights. He is cheated by the crime boss Mr. Big (Sammo Hung Kam-bo) while trying to buy a fake ID, so he steals the man's drugs and runs into the Kowloon Walled City. Soi Cheang puts him in front of Cyclone (Louis Koo), the crime lord who rules the place and is kind to him, and the two start to depend on each other.
