I didn't make it to Hong Kong til 1994 so this famous Kowloon walled city had already gone but it's legend hadn't. It was the equivalent of a large block of properties, within properties - a mass of alleys, corridors and tunnels in which the law was enforced in a very different way from the outside. This story starts with a battle that sees control pass from "Jim" to "Cyclone" (Louis Koo). There's now a truce of sorts that exists between the bosses and the outside world, but that's about to be thrown into turmoil by the arrival of "Lok" (Raymond Lam). He works hard to get an official ID card but is fleeced by "Mr. Big" (Sammo Hung) and escapes with a bag of his cocaine into the walled city. That's where he encounters it's ruler and his sidekick "Shin" (Terrence Lau) and where his willingness to work and his fortitude ingratiates him with the boss. On the outside, "Cyclone" has a business relationship with "Chau" (Richie Jen) who has really only one purpose left in life. That's to avenge the murder of his family by the now dead "Jim". The focus of his revenge is that man's own son - but nobody nows what happened to him. Well, swiftly you can add two and two and get "Lok". Loyalties are now tested, friendships challenged and forged whilst the fragile peace is soon in tatters. With battle lines drawn and ambitions clear, it's all out war and the action mounts up. This is a sold end-to-end martial arts film with plenty of nimble and lithe combat; acrobatics and bodies that must be made of skin-clad tungsten steel. It's got a little bit of mysticism and embodies human nature, whether benign or not, quite entertainingly and by not just throwing itself about, but by at least trying to create and develop the characters. The denouement takes it's time and does become a bit repetitive, but as a quickly paced drama it really does fly by for two hours. Honour amongst thieves - but always sleep with your back to the wall.
