Enterprise fever grips the school. Alex asks for his car back and when Mrs Bassinger declines, Tigger says they need them "for their enterprise project". Knowing he is bluffing, Mrs Bassinger invites the foursome back to her office to present their plans. Alex suggests they organise an official race, with sponsors and pupils paying to take part. They set about putting a presentation together. Kathy hears about a school which turned its canteen into an after-school cafe where pupils could hang out and do homework. Maddie announces her own plans for a "cool after school cafe". Kathy can't believe her ears and a furious exchange follows in the common room - Kathy is sick of Maddie always bossing everyone around.

Dawn and Kat discover Grange Hill was once a church school, and weddings sometimes took place. They try to get out of Malachay's presentation - instead, he embraces a "weddings through the ages theme". Dawn finds a way of incorporating her idea into Malachay's. Emma tires of Tanya's vanity; she's now complaining her ears were uneven! Mr Fox takes a photo of her, and mirrors it, to prove she was perfect as she is. Togger signs Tanya's name up for the school council - "she's always telling people what she thinks". Jeremy carpets him for always giving her a hard time.

Andrea swats up for her history test reading Dawn's notes - Dawn took the same test in Year 8. Chloe sees an opportunity to cash in - and sells the answers for £1 a time! In the event, the questions are different from what they were expecting! Chloe is forced to hand back her profits to irate punters. Mr Fox gives them a dressing down, then Dawn comes along and realises what she'd been up to. Holly is impressed when Martin talked to her in sign language. Tanya finally returns Togger's shirt - but the colours ran and it is pink! Tanya defiantly wears a tracksuit in PE and when ordered to remove it, reveals a top and skirt that were too small for her. When Tanya threatens to take her skirt off, Malachay sends everyone inside - in a fit of rage Togger fires a rounders ball at Jeremy.

Mrs Bassinger listens intently but isn't quite convinced by Year 8's proposal. Alison swings it for them, convincing Mrs B the car ban would lose the school money. Malachay gives Tanya and Togger four detentions; when they hear Dawn and Malachay discussing cast for the video, they ask if they could do that instead. Malachay agrees - but Togger and Tanya are horrified to learn they'll be playing bride and groom!
