Strange noises fill the Dumping Ground in the middle of the night. Jenny investigates, but it turns out to be Tracy, who is looking through the files for her mum's (Annette Bentley) address. Jenny and social worker Elaine explain to Tracy that her mum knows where she is, but they can't give her mum's address. Soon after, Tracy and Justine compete in a game of dares to win back Tracy's room. Justine covers Jenny in flour, Tracy fills Mike's boots with cheese sauce, Justine steals Jenny's clothes while she is having a shower, and Tracy tries to climb a tree, but Mike climbs after her and pulls her down. Tracy dares Justine to put a worm down her trousers – which she does – but Justine tells Tracy to eat a worm. Tracy hates the idea, but does it, and throws it up later. Justine quits the competition and says Tracy can have her room back. However, after Justine has packed all her stuff, Tracy tells her she can keep the room as she likes her new room better, infuriating Justine.

There is much activity in the Dumping Ground. They are expecting a visitor – writer Cam Lawson, who is writing an article about the care home. Tracy is especially excited, as she wants to be a writer. She even steals older girl Adele's makeup to try to impress Cam. When Cam arrives, she is surprisingly unglamorous, but Tracy is still excited to meet her. However, Justine ruins it by making fun of Tracy's life book in front of Cam, prompting the two to get into a fight and Tracy to be sent to her room. Before Cam leaves, she goes to Tracy's room to make up with her, but Tracy is furious and makes her leave. When Tracy discovers that Cam has left her a fairy cake, she thanks Cam out of her window just as she is leaving, and realises that Cam likes her. Meanwhile, Mike is stressed about Cam's visit and asks for Adele's help to get the house ready. He offers her many things, but Adele will not budge until he agrees to give her an extra late pass for that week. She eventually complies, only to discover that Mike has finished it all.

Tracy is becoming increasingly frustrated with Cam, who has still not decided whether or not to foster her. Banned from phoning her, Tracy enlists Ben's help to go to see Cam in person. When they arrive at her flat, Cam is out, so Tracy and Ben rearrange the furniture, play music and eat her food. Meanwhile, Justine and Louise go head-to-head with Zac and Ryan when they begin washing cars for money, leading to a big waterfight outside the DG.

It's Peter's last day at the Dumping Ground before he goes to live with Terry and Jill. Everyone attends his party, except Tracy, who is secretly looking after two giant African land snails for the weekend. Later that night, it's full moon, and Zac has hung up garlic all over his and Ryan's bedroom so as to scare off vampires. And the snails escape from their cage. So, soon enough, everyone is creeping about all over the DG.
