The gang head to a music festival to support young Adam and his band. Jenny's determined to make the most of her festival experience; living it up with Ellie and her college mates. As Pete's suspicions grow about Jenny's erratic behaviour, she struggles to keep a lid on her secret.

Adam realises the baton has well and truly been passed to Matt when he's the one chasing girls and Adam's at a loose end. He challenges Karen to relive their youth and the two of them try to out-festival each other with unexpected consequences.

David's bank balance is critically low; the silver lining of his break-up with Nikki is that she booked a swanky yurt to stay in for the festival. He keeps his split with Nikki under wraps, too embarrassed to yet again need to rely on his friend's charity. David makes friends with a cookie seller, not realising how much of a taste of festival life he's about to get.
