Drinking buddies Fai (Louis Koo), Boo Sam (Simon Yam) and Mok (Honglei Sun) hatch a scheme to rob a jewelry store. But their plans change when a mysterious figure offers them wealth beyond their wildest dreams if they'll steal a box hidden under a government building instead. Three acclaimed filmmakers -- Tsui Hark, Ringo Lam and Johnny To -- each direct a third of this high-speed caper film. Ka Tung Lam and Kelly Lin co-star.
