That movie filmed in denver?

Question

I remeber when I was a kid seeing a movie filmed in Denver about a bunch of kids who go on a rampage against the PTA. I only remeber the ending when they had locked all the parents instide and burned cars and stuff outside. I also remember at the end of the movie the one kid taken away by a prison bus while the others waved goodbye on an overpass bridge. I can't remember the name of it and would like to rent it on Netflix. Maybe late 70s early 80s.

Answer 1
