A ruthless Assassin (Edison Chen, INFERNAL AFFAIRS, INITIAL D, THE GRUDGE 2) with no name is plucked from the underworld of Cambodia and unfurled on the streets of Hong Kong with a mission to execute a single target. Trained from a child to be an inhuman, silent, faceless killer, this wild dog has only one weakness - human error. Soon a trail of bloody carnage separates the dog from his bait and the hunter becomes the hunted as the police and the underworld close in for a bloody finale! Brutal, uncompromising and with the ferocity of a punch to the throat, DOG BITE DOG is a visceral and dazzling odyssey reminiscent of Chan-wook' Park's Vengeance Trilogy and the great works of Ringo Lam and John Woo, this is undoubtedly one of the most violent, thrilling and exhilarating action films you will ever see. Brace yourself - this dog's bite is much worse than its bark!
