In the throes of a sold-out concert, charismatic rock god, Jack, invites his bandmates and groupies backstage for an impromptu jam session. But this isn't your typical after-party. As the music reaches its crescendo, so do the participants, shedding clothes and inhibitions. Jack's powerful vocals are echoed by the wet, eager sounds of his fans, their bodies grinding and writhing in rhythm. With instruments discarded, they create their own symphony of pleasure, a raw, unbridled concert of flesh and desire.
