 N3 is away in the countryside on an orienteering course. Everyone pairs off, but Roland finds himself with Mr. Baxter, which at least seems preferable to being with Janet. Fay and Annette have a slender lead over Zammo and Kevin, which they are determined to maintain even if it means cutting across a wood, and misleading the enemy. Roland seems to be doing rather better at Orienteering than Mr. Baxter. Mandy and Sarah hide a control marker which causes Roland and Mr. Baxter to get hopelessly lost. Mr. Baxter tries to climb a steep slope, but slips back and is incapacitated. Back at camp, there s growing concern at the missing pair, and a search party commences. The teachers fail to find them and send everyone else back to the hostel, while a proper search and rescue is arranged. At the hostel, Sarah and Mandy admit they hid the control marker. As evening turns into night, things are looking grim - but then Roland s whistle is heard, and the two strays are found. A telephone call is placed to the hostel, and there is relief all round. Roly comes back to a rapturous welcome...
