Remember the custom van craze of the 1970's? This is a "vansploitation" film, one of several from that period. The story here is that it's the dudes vs. the chicks, the guys are driving customized vans and the chicks have customized pickups. And there's skateboarding in this picture, which also made its comeback during that time period // aka "SUMMER SCHOOL", that's the title on the print I saw. Cheezy nostalgic fun.
