In the future, a health nut and his tag-along girlfriend become trapped in a drive-in theater that has become a concentration camp for outcast youths.
Starts by ticking you into thinking it's going to be one of the 47 million _Mad Max_ rip offs that was released around the same time, but quickly takes a left turn into "poignant social commentary". Keeps the punks though, so that's cool.
_Final rating:★★★ - I personally recommend you give it a go._
