 It s the last day before half term, and a sponsored bike ride is in the offing - but Annie and Emma can t find their partner in chrome, Tanya. They give a radio broadcast about their recycling aims, but Tanya s absence makes it less effective. Togger, who considers the whole thing a race, immediately turns around the race signs (in time-honoured Grange Hill style!) to confuse the opposition. There s also the matter of the French Exchange kids arriving. As the bike ride starts, it becomes evident that Tanya has other plans: she s all dressed up to meet Jean on an unofficial stop. Chloe shows her sponsorship form to Sammy - just 3 sponsors doesn t seem too impressive. Maddie catches Taylor chatting up yet another girl and tells Karen. Baz has to fetch his father s medicine, and is once again late for swimming, facing Mr. Malachay s wrath. Early in the bike race, Chloe comes off her bike with a bad leg, and Mr. Fox suggests that Sammy does the race on her behalf. Togger and Andy notice Tanya going off the track and assume she knows a short cut, and follow her. Dawn s overdue on the script, and is nagged by Spencer and Kathy to show it - under pressure she reveals that what she s written is rubbish. Back at the race course, Tanya changes into her flash gear and waits for Jean. She comes across Simon, a man who says he s a friend of Jean, and that Tanya s boyfriend is delayed. He says he is going back to the port where Jean is waiting, and will be delayed for several hours. She asks if she can go back to the port with him to see Jean, and he agrees. As Tanya walks back with Simon, she finds he seems to know a lot about her. Back at school, Taylor provokes Baz into a fight - and it s the last straw for Mr. Malachay, who takes Baz off the swimming team. Walking with Simon well off the beaten track, Tanya s getting suspicious and nervous, and sends a text to Jean - she immediately hears the tone sound on Simon s mobile. She runs, but he catches her; in the distance, Togger hears her yells and gives chase, seeing her get dragged into the back of a van. Andy calls the police, and Togger bikes in hot pursuit of the van. Back at school, reading Dawn s script, Spencer gives some "constructive" criticism - Maths not being his strong subject, he says the script should be 57% bathos, 33% pathos, and 29% Athos. (Kathy points out that Athos is one of the Three Muskateers). The van, with Tanya pounding on the doors in the back, reaches a point in the road where the Grange Hill bikers are blocking the path - confused by Togger s sign-changing trick. Mr. Malachay is about to clear the road for the van, but Togger calls out Tanya s name, and Simon panics, pulling Tanya out of the back of the van, and tears off before anyone realizes what is happening. Togger catches hold of the terrified girl, and then her friends Annie and Emma put their arms around her. Back at the script writing, there s a moment when Spencer seems to be about to say something that Kathy wants to hear - but instead he just tells her that he couldn t be without his Assistant Producer. With the race over, and police called to the school, Chloe reveals her game plan - her hidden sponsorship form for money she intends to keep. As Tanya is taken away by the police, Emma and Anna wonder at what might have happened, and Togger and Andy are glad that they changed the signs which brought the van to a stop...
