On your afternoon of his kid's birthday, William"DFens" Foster is trying to arrive at your house of his estranged ex-wife to visit his daughter. His car breaks down, so he makes the decision to walk and leaves his car in a traffic jam in Los Angeles. The owner does not oblige, tipping Foster on the edge, although he tries to get some change for a telephone call and belongs to your convenience store. The shaky Foster, therefore frustrated begins to psychotically and lash out against them.
