Based on the description, this seems to be a vigilante action short. Without the description, though, you might interpret it in a very different - and far less honorable - way, if there's even such a thing as honor in killing.
Dignity tells its entire story in under four minutes, which leaves a lot out. We don't know what happened before or what truly drove the main character to commit the unthinkable. There's a small clue in the form of a photograph, but it doesn't give us much to go on.
As a huge fan of the Death Wish movies, I was really excited about this one, but the execution felt too dark for my taste. That said, I have to admit, I wouldn't mind finding a bar like this where you can just order a drink and not have to pay, lol!
