In an isolated village in the north west of Ireland, a murder investigation begins when Garda Barry Roche finds a body buried in the bog. In the most personal of cases, Garda Conall Ó Súilleabháin discovers it is his mother, Sabine, who has been missing for 15 years. Conall is forbidden from working on the case, but is drawn into the investigation by a determined young journalist Ciara-Kate, who is using her true-crime podcast to expose the village\'s deepest secrets. As they unravel the truth, they must confront a community bound by silence and its own moral codes.
