The man who met himself (2005)

Who is Stephen Maker? Did he fake his own death, or do doppelgangers really exist? A mysterious call, a photograph of a man and a private detective compelled by the one case that has finally got to him. One stark but brilliant day in London, Austin Peterson takes a job from an anonymous client, a demand he knows he should refuse. He uses the feelings of the woman who loves him to get information. But this only raises more questions than it answers, leading Petersen deeper into the maze.
