Simon is a recent college graduate who has recently broken up with a long term girlfriend. He wanders the streets of Paris, brooding over his former partner, Michelle. Along the way, he meets a prostitute, first as a client, and later as a roommate. He comes up with an idea for her to make easy money through blackmail. The problem is that the movie meanders with bad direction and no real conclusion. Simon is a man with no emotion, and, in the end I did not care about him at all, or any other character he encounters on his meaningless travels. I could not wait for film to end, and there is no reason at all to sit through Simon Killer.
