Very dark movie

Night, rain, soft light, a glass of whiskey, corpses, corpses, corpses: the main character does not know who he is, when it comes to the mind next to the corpse of a policeman, and a revolver lying beside the body. It seems that our hero is a murderer. But he can not remember anything ... The hero gets into the brutal world of deadly deception and boundless immorality in the world where the filthy lies is just sex, and the only thing you can be sure - is that all - not what it seems.
