We've seen the madness that lurks inside the cells of Arkham Asylum in comics animation and video games, but until "City of Scars," we'd never seen it in a fan film.

Here's the 30 minute fan film's official synopsis:

When the Joker escapes from Arkham and murders the parents of a young boy, Batman recalls the pain of losing his own parents as a child. He is pushed past his limits to the point where his focus becomes revenge on all who stand in his way, including many of Gotham's underworld. Finally, Batman is forced to look at the psychological profile of his own mind and except the consequences of his life to find resolve.
