This is an awkward Italian mash-up of "Escape From New York" and "The Warriors." The main character is named Trash and is played by a 17 year-old bodybuilder with no previous acting credit. So, yes, you should see it.
More Warriors than Escape from New York with a little Road Warrior on top. If you take away those film's budgets and put em in a blender you'd get the Bronx Warriors. Fun early 80's Italian B movie. Soundtrack is awesome too.
