Bringing together three of Hong Kong's most prolific directors, Ringo Lam, Johnny To and Hark Tsui, 'Triangle' tells the story of three financially troubled friends who get given a map and decide to end their problems by digging up a hidden treasure from under the HK Legislative Council building. With each director taking a third of the film to make his own, this high octane action-thriller is occasionally a bit disjointed, but in the main holds together surprisingly well.
