The starting point for the film is an 8mm amateur home movie from 1965, where Mick Jagger, Keith Richards and Brian Jones from the Rolling Stones attends an after-concert party with local musicians and pop fans. For some the party never ends. Immortalized on a forgotten home movie, the party-goers try, forty years later, to make sense of these memories, and the eternal question of 'What could have been?'
