Abby travels to Waterhouse, a nearby manor- and into a land dispute between an aggressive group of teenage boys and Jimmy Garland, a former army officer, which obstructs her attempts to discover whether Peter is there or not. Tom, Al, Sarah and Najid find themselves attracted to the comfort and security within Samantha Willis' community, but Al falls afoul of Samantha, and is ejected from it. Can Tom prove himself to Samantha, and what about the complication of his criminal past? Meanwhile, Anya and Greg confront some unwelcome visitors, and learn some useful lessons about group solidarity.
