Here is the synopsis for Part 1:
"...it’s been a decade since Bruce Wayne hung up his cape, following most of the other superheroes who had been forced into retirement. Facing the downside of middle age, a restless Bruce Wayne pacifies his frustration with race cars and liquor – but the bat still beckons as he watches his city fall prey to gangs of barbaric criminals known as The Mutants.
The return of Harvey Dent as Two-Face finally prompts Wayne to once again don the Dark Knight’s cowl, and his dramatic capture of the villain returns him to crime-fighting – simultaneously making him the target of law enforcement and the new hope for a desolate Gotham City. Particularly inspired is a teenage girl named Carrie, who adopts the persona of Robin and ultimately saves Batman from a brutal attack by the Mutant leader. Armed with a new sidekick, and re-energized with a definitive purpose, the Dark Knight returns to protect Gotham from foes new...and old."
Adding to the element of fandom is the fact that Peter Weller, best known for his role as Robocop in Robocop and Robocop 2, will be voicing the older Bruce Wayne/ Batman in both animated adaptations of The Dark Knight Returns.

Batman: The Dark Knight Returns, Part 1 will be available in Blu-Ray, DVD, and Digital download this coming September 25th.
