Teenagers David and Emily are inseparable friends, who live year-round on a crummy seaside caravan park on the East Anglian coast. They play games of chase among the caravans, scare sheep in surrounding fields and steal from the sweet shop on site. The friends, although the same age, are at different stages of their development; he still looks boyish, she is already flirting with Steve, the much older security guard on site. But the pair are equally emotionally inarticulate and struggling to understand their nascent lust; as the increasingly dark story unfolds, we understand that The Scouting Book for Boys is a snapshot of that moment in our lives when our minds and bodies are caught in a battle between child and adult.
