Noted Hong Kong action director Johnny To spins this ultra-cool cat and mouse game between a very tenacious cop and a super thief with 72 hours to live. After brilliantly swiping diamonds from an insurance company, a master criminal (Andy Lau) inveigles Inspector Ho (Lau Ching-wan) into being his unwitting accomplice. Later, when the two confront each other, the thief has another trick up his sleeve. ~ Jonathan Crow, All Movie Guide
