As the gang heads off to a music festival, Jenny is determined to make the most of it, but Pete is suspicious of her erratic behaviour. David enjoys the perks of festival life a little too much, while Adam and Karen discover that reliving their youth has its consequences.

Jenny's secret is finally out and the gang rallies round to support her, while David's situation goes from bad to worse, but he is too proud to ask for help. In a desperate attempt to prove their kiss meant nothing, Karen sets Adam up with her illustrator friend Caitlin.
