Three maestro Chinese action directors--Ringo Lam, Tsui Hark, and Johnny To--co-helm the adventure saga TRIANGLE. The film actually constitutes a film serial, divided into thirds, with each filmmaker responsible for one episode. Three drinking buddies, Fai, Sam, and Mok, are visited one dark and stormy night by a strange old man who dazzles them with the tale of an ancient treasure. The artifact in question--worth untold amounts of money--lies buried beneath an almost impenetrable government facility. The retrieval mission is theirs, if they wish to accept it, and if they can claim the treasure, they get to keep it. Indeed, the "loot"--a magnificent robe of interwoven golden strands, its monetary value inestimable--outstrips everyone's expectations. But in time, the friends' greed and selfishness begin to overshadow their considerations of loyalty, trust, and friendship.
