DI Lorne Simpkins and DS Pete Childs are called to investigate the death of Jenny Bartlett, who’s decomposing body is found in a wooded area. When Lorne informs Jenny’s parents of her death they are understandably shocked but also confused by the news as they were under the impression their daughter was out of the country, working as a volunteer in Africa.

Delving deep into Jenny’s personal life leads Lorne to Jenny’s former boyfriend, Simon Killon, after Lorne discovers they had a secret liaison in a restaurant shortly before her death. But is he guilty of Jenny's murder?

After learning what traumas Simon himself has encountered lately, Lorne has her doubts that he’s the culprit. However she finds it hard to disprove the evidence pointing in his direction.
