After leaving home 10 years ago, detective Lauri Räihä is sent to investigate the murders of two men in the small northern Finnish town where he grew up. The investigation offers a way to escape couples' therapy and his failing relationship with his husband. But going home forces him to face his family and the deeply religious Laestadian community that rejected him many years previously. Together with his partner, Sanna Tervo, a carefree soul on the surface, but also someone who has their own difficult past, Lauri seeks answers to the case only to discover other truths about himself, his home town, and whether one has the power to forgive all sins.
