Mythic, controversial—the worst rock festival of its time!

December, 1969. Woodstock and the Flower Power wave have swept the east coast of America a few months earlier. In reponse, the west coast decides to pump up the decibels for a festival that strives to be legendary. The era's greatest stars are slated to take part. No way are Jenny and her buddies missing the concert of the century! In their Volkswagen van, the easygoing ambiance is redolent of mary jane. 300,000 people are expected to turn up for the peace, love and rock’n’roll extravaganza at Altamont Raceway. Shortly after the group of friends rolls up, the first altercation breaks out—an ill omen if ever there was one.
