even if you have seen this film and think it is quite rubbish then. your  probably wrong because to fully understand all the hard clues takes at  least two or three times to understand this, the first five minutes of this  film is pretty rubbish , straight from their it gets quite good it's about  four teenagers who are drunk and is driving a pretty expensive bmw end up  running over him,thinking that he's dead they decide to dump his body in a  sea, around the same time some ordinary man sucides into the water, weeks  later when it comes up on the news that a dead body was found in the sea,  the four teenagers think it's him, but it isn't and the man they ran over  know who they are and decides after a year to haunt them down 1 by 1 he  decides to kill them the same day he got ran over but first he has to toy  with thim and to show them who's boss.for a small 10 dollars it's definatly  worth it.
