Alun arrives in Glasgow to play a gig at The Edge, a comedy club run by would-be promoter Max T. Max T should be looking after Alun, but he already has his hands full trying to keep Sandy Cervo, his second cousin and business partner, from taking over the club. In a bid to sort out some 'poontang' for himself and Alun, Max invites Eva, a psychiatric nurse and her photographer friend Christina along to the gig.
