It's a pretty ridiculous movie but it has a good moral.
A homeless vigilante blows away crooked cops, child enthusiast Santas, and other scumbags with his trusty pump-action shotgun. Street justice will indeed prevail. Based on a fake trailer made for the 'Grindhouse' film by Quentin Tarantino and Robert Rodriguez
Detailed Plot:
A vigilante homeless man pulls into a new city and finds himself trapped in urban chaos, a city where crime rules and where the city's crime boss reigns. Seeing an urban landscape filled with armed robbers, corrupt cops, abused prostitutes and even a child enthusiast Santa, the Hobo goes about bringing justice to the city the best way he knows how - with a 20-gauge shotgun. Mayhem ensues when he tries to make things better for the future generation.
