Life at the Dumping Ground continues without Tracy who is on holiday with Cam. However life isn't great at the Littlewood home. Justine is reminded of how badly her dad let her down in the past when she is forced to move out of her room to make way for her cousin John and his dog Bruce who are moving in with them. Justine returns to the DG where she hopes to find security, but gets more than she bargained for when she discovers she is sharing a room with new girl Rebecca.

Strange belongings are going missing in the DG. Who is the crook? Is it Lol who is trying to get used to life without Bouncer? Or Justine and Rebecca who would do anything to set the other up? Or Wolfie who looks like he's had enough and is packing a bag to leave the DG for good?

Chantal leaves with her Dad, creating a huge split for the Wellard threesome. Elaine brokers a meeting between the stubborn Justine and her Dad - but Justine feels forced out by her cousin John and they get nowhere.

Elaine runs an Open Day at the DG. Roxy aims to cause havoc with her sidekick Rio, but he proves an unwilling partner - even donning a clean shirt to impress potential new parents. Layla and Wolfie try to free Mike's free-range pig! The day ends in chaos but nothing prepares them for the shock return of Tracy Beaker to the Dumping Ground. Tracy has decided that she can't live with Cam anymore because Cam wants her new boyfriend Gary to move in with them.

Jackie returns to the DG apprantly injured. She doesn't seem very happy due to the arrival of her Grandpa's best friend, Flying Freddie Murpher and Tracy tries to find out what's wrong. Meanwhile Crash isn't very happy after receiving a letter from his dad.

Tracy gets a knock to her head and life at the DG is turned on its head with the adults behaving as their charges would, for one whole day of havoc at the DG. Nothing is the same - even Milly has an attitude. Tracy gets more than she bargains for when she wakes up with a conscience about Cam.

Shelley returns to the DG and is dismayed at the bad behaviour going on. She insists that the kids spend the day thinking about their bad behaviour - boredom turns to fantasy as the kids imagine how they'd get their own back on the adults, as they star in their favourite films.

Alice and Layla attempt to find a home for a stray dog, while Tracy writes an article on life at the DG that shows Cam just how much she enjoys living there. The kids are horrified when their dream foster parents decide to take the dog home instead of one of them.

When Mike introduces Bouncer as the new DG chef, the kids are thrilled - until he turns Jamie Oliver on them and produces manky 'macrobiotic' health food. The lack of additives in their diet has a dramatic effect on their behaviour - Rio starts doing yoga which is more than Roxy can cope with.

Just as Lol prepares to leave the DG for the halfway house, Tracy agrees to spend time with Cam and Gary and, to her surprise, they get on brilliantly... until Cam drops the bombshell that they're getting married - this is way too much for Tracy to handle and she wants nothing to do with the 'sordid' affair.

Cam is heartbroken that Tracy won't be a part of her special day, but thanks to Crash and Jackie's wise words Tracy finally sees the light. As she packs her bags to leave the Dumping Ground for good, a brand new version of Tracy Beaker (Amy Sneaker) arrives at the care home - same attitude, same actions! Life goes on regardless.
