All the Sins

Lauri, a young crime detective, is saved from couples therapy when he is sent on an assignment to his childhood surroundings in Northern Finland, where the conservative small town of Varjakka is shaken by two murders.

The people of Varjakka search for a missing father of a family. At the same time, the detectives' work is hindered by personal problems: Sanna is contacted by an unexpected party and a friend from the past blames Lauri for the misfortunes. The atmosphere among the townspeople starts to turn tense.

Sanna receives a message that she has been afraid of for a long time. Lauri tries to comfort his colleague, but in the meantime he makes a breakthrough in investigative work. The community of believers work through their grief.

The killer has mastered the art of diversion, and Lauri and Sanna have to break bad news. Lauri receives an unexpected visitor and she begins to hope for change. A strange accident by the sea brings the media together in Varjakka.

More evidence and suspicions come out that suggest the crimes were committed by two perpetrators who may have a common enemy. Meanwhile, a rift opens up between investigators Lauri and Sanna.

While the congregation of believers gathers, Lauri's old wounds are torn open. Likewise, Sanna has to deal with a trauma from her past. The question arises as to whether forgiveness is possible.
