The great Johnnie To (The Mission, Running Out Of Time, The Heroic Trio) directs this intriguing murder mystery with a touch of zen. Andy Lau (Infernal Affairs, The Duel), in his most daring role to date, is Biggie, a huge, muscular Buddhist monk who knows kung fu and somehow has "Karma" - the ability to see things before they happen. Biggie's unusual characteristics soon arouse the interest of policewoman Yee (Cecilia Cheung), who gradually falls in love with him. She agrees to help Biggie track down the murderer of his childhood friend. But when Biggie's karma foresees Yee's own demise, he has to do everything in his power to stop destiny.
