Overton: a tiny village in the English countryside. Farming is its bread-and-butter. Racehorses are its beating heart. When the body of a local teenage boy is found underneath the wheels of a tractor, the villagers in this remote community - his friends - are forced to open up their world.

Suspicions are running high after the discovery of Cal's body. Cal's friends - Rob, James, Tina, Janine and Annie - are questioned by the police about what happened on the night of the murder.

It's Cal's funeral and the traveller community are preparing to put his body in the ground. Tina reaches out to Eli, but he's haunted by the unexplained changes he'd seen in Cal in the last few years. When Chris, who was in care with Cal, appears at the graveyard, Eli follows him hoping he has some answers, but uncovers some disturbing secrets.

Tina is shocked when Dominic offers her a chance to ride Blackout in a big race. A race Blackout must win if Jackie is to sell the horse and save the farm. But Dominic's agenda seems increasingly sinister.

It's the annual Warwick Farm pheasant shoot and, in the circumstances, Jackie wants to cancel. James is adamant he can handle it, but that's before Rob interferes.

James is in custody and the police remain convinced that James is guilty, but Ruth has doubts that draw her to Elizabeth Marshall's hospital bedside.

With Ian dead, Ruth is removed from duty on the murder squad and placed back on the beat, where she finally has to confront the possibility that she will never find Cal's killer.

In the final episode Ruth is caught between loyalty to the Traveller community and exposing who she believes is the killer. Will she do the right thing?
