American Animal (2011)

Some of us evolve slower than others.

When Jimmy (Matt D'Elia) finds out his best friend and roommate (Fletcher) is leaving, he sees this as a betrayal of their perfect way of life. Over the course of a night full of drinks, drugs and women, the two men engage in a classic battle of wills as James prepares to enter the real world and Jimmy falls deeper and deeper into his world of isolation and make-believe.
