Well, I watched the whole thing but I can't really say what it was all about. The picture resembles one of those episodes of 'The Monkees' television show from the Sixties, and since this came out in 1970, maybe it took some inspiration from that program. The working premise has to do with a deadly gas that has eliminated the world's population over the age of twenty five, thus setting up a preview of 1976's cult hit, "Logan's Run". Basically, from what I could gather, the story pits a band of hippie, counter-culture, New Age zealots against a team of high school football players led by a would be warrior named Jason (Alex Wilson). A handful of names who became better known after appearing in this travesty include Cindy Williams, Ben Vereen and Talia Shire, but how they landed here will remain a mystery to my mind. With all that, it should come as no surprise that Roger Corman was the director here, working off a screenplay by George Armitage. It's a rare Corman film I'll rate higher than a '5' here on IMDb, a rare exception being 1960's "House of Usher" with Vincent Price. For perspective, this was probably a little better than his "Last Woman on Earth" and about on a par with "Attack of the Crab Monsters". And lest I forget, appearing as well, fresh off their 1969 gig at the Woodstock Music and Arts Fair, you'll see and hear Country Joe McDonald and his band, but whether that adds or subtracts from the ambiance of the film you'll have to decide for yourself.
