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. He is joined by a partner, senior detective Sanna, a pleasure-seeking woman who has never been so far north before.

Lauri makes a breakthrough in the case and consoles a shell-shocked Sanna. Violence mounts while the local religious community grieves.
