The plot of the 30-minute film, which debuted today at Daily Motion, is summarized here:
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 accept the consequences of his life to find resolve.
It's a new Batman film. Who are you kidding? You know you want to watch it.
