The Thorns are living a happy family life in North West London when a tragedy changes their lives for ever. Rosa takes a job as a supply drama teacher in the tough local comprehensive to which her two teenage children - a seventeen-year-old son and a fourteen-year-old daughter - also attend. Then someone begins to stalk her daughter and sinister events start to unfold. Who could be the perpetrator of such malice? Is it the schizophrenic gardener who tends the park opposite their house? The headteacher is very interested in the attractive Rosa. Then there are her neighbours, who, on the surface seem kindly, but why are they having strange nocturnal gatherings? The urban world is becoming a sinister place for the Thorns, and is Rosa strong enough to protect her life, but more importantly, the lives of her adored children?
