Detectives Cadi John and Owen Vaughan investigate the brutal murder of a former school teacher, but a group of local teenagers knows more about what happened than they are letting on. 'Nail-biting, (and) confidently stylish' (The Guardian), this compelling Welsh crime drama has been hailed 'best in class' by the New York Times.

When a body is found in a river, Cadi leads an investigation into the lives of two brothers. The brothers have secrets to hide, a harrowing history, but you can't outrun your past. --

As Cadi delves deeper into Mia's relationship with a boy who killed himself years ago, Mia and Connor reel from what happened at the gas station. Later, Cadi is called to the scene when another body is discovered.

With Lee in custody, evidence builds against Mia, but she still evades police efforts to find her. Cadi rushes to the hospital when she hears that Connor is in intensive care after the incident at the lake.

The community gathers together at a local church for a memorial service for Geraint. Cadi and Owen attend in the hope of securing new leads. Connor's overwhelming guilt reaches a breaking point.

While dealing with her father's failing health, Cadi attempts to track down Dylan's truck. With Megan still locked up, Dylan's neighbor makes an unexpected visit, and Lowri struggles to recover from her attack.

Admonished by his domineering mother, Iona, Dylan skips work and develops an unhealthy obsession with Lowri, a young nurse. Meanwhile, the detectives interview Mali's friend Sara, who points them to Mali's dangerous ex-boyfriend.

DI Cadi John investigates the death of a young woman found in a river, who appears to have been shackled for some time before her demise. Cadi and her colleague DS Owen Vaughan identify the body as Mali Pryce, a troubled girl who disappeared years ago.

When Megan is reported missing, Cadi and Owen are certain her disappearance is connected to the other cases, but they are no closer to discovering Dylan's identity. Dylan's daughter, Nia, talks with Megan and tries to help her escape.
