It's about this man and he writes this diary!He messes up somebodies life and he looks in his diary then all of a sudden he's in a different life (still as hiself) and he ruins another persons life so he goes back to his diary again and returns in a diferent life.This carries on...Until he realises that the only way that he won't mess up anyones life is if his mum had got him aborted so he returns to his diary but not into another life as he never existed.GREAT FILM BUT INCLUDES SEXUAL SCENES AND IS DEFINATELY AN ADULT FILM!
