When the body of student Josh Tate is found dumped in a ravine, the investigation into his stabbing uncovers a very different man to the quiet character described by his flatmate Spencer. It emerges that Josh was infatuated with Spencer's girlfriend and had been manufacturing Ecstasy for club owner Liam Fallon. Meanwhile, DI Morton's ex-lover Martin Hexton has arrived, claiming to be working on a local case. When Fallon comes under suspicion as Josh's murderer the detectives break into his flat and find him badly beaten - and to complicate matters, it looks as if Hexton is responsible.
