Dolly, Hayley and Marco get a taste for trouble when they realise just how much fun being bad can be. Tracy thinks they're clueless and brags about all her famous scams – cheese sauce in wellies, running round the garden with the head care workers knickers on your head and eating a worm, to name a few! The little kids are in awe and decide to set up 'The Beaker Club'. However, The Beaker Club's actions nearly cost Dolly her soon-to-be foster family. When the foster family in question turn up at The Dumping Ground and the Club drop ketchup-and-flour bombs on their heads, not realising it's Dolly's soon-to-be foster family, their actions soon bite Dolly on the bum.

Tracy plans to go skateboarding with Jackie, but she has double-booked herself. She also unwittingly promised Cam she'd spend the day with her. Cam lays a guilt trip on her, so a reluctant Tracy cancels her day out with Jackie and lets Cam drag her off to an open day at the local Art Centre. The Wellards see an opportunity for mischief, and entice the dejected Jackie to steal the kids' files and burn them. Jackie gets caught, but she and Crash hatch a plot to pay them back. Meanwhile, Tracy enjoys herself more than she could ever have imagined.
