Swindled (2011)

Eddie Oliver is unemployed, lives by himself, and never goes outside. He spends most of his days pondering things that would never cross most people's minds, and trying to re-connect with his girlfriend, Kim. Eddie is very paranoid, and unstable. He loves Kim very much and badly wants her to know how deeply he feels for her. But his mental instability and paranoia just might prove to be too powerful an adversary for him to overcome.
