When the body of young PE teacher Jason Bowe is discovered in woodlands adjoining a prestigious boarding school, UCOS are asked to investigate the case quickly and discreetly. However, with the school busy preparing for a visit by prominent MP Geoffrey Parks, its headmistress is less than happy about the UCOS team's presence there.
When Standing makes a discovery about another teacher, the team realise that they're dealing with a much wider and more complicated series of crimes that go back many years.
Meanwhile, Standing pushes Pullman to find a replacement for Halford, and Lane struggles to cope with the secret he's been keeping.
