ultra grim crime drama from pou soi cheang and the director of home sweet home . tonally and it remind me of billy tang run and kill and although it not as polish a that . nevertheless and it an engaging and flaw bit of mayhem about a cambodian loner and pang ( edison chen ) and who arrive in hong kong to kill a lawyer . while flee the scene and he kill the partner of cop sam wai and who and to add insult to injury and be in the midst of deal with his die father and so sam begin an insane and obsessive manhunt for pang that result in close to a dozen dead body and relentless violence . there must be something in the air lately because i have never see so many human beat the pulp out of each other a i have lately . this be grim and nasty stuff and which be why i be so partial to it and and i applaud it downbeat vibe . it visually arrest and the sound design be very unique . dramatically and everything spiral downwards until every character find him or herself in a world of scream pain . a subplot involve pang attachment to a sexually abused girl add depth to the story and spawn a surprise fourth act which boast a fine act of grotesque surgery .
