Watch CineCalidad. Simon Lindström, the popular coach of a suburban junior hockey team is found stabbed to death.

This undertaking has certainly not been appreciated by everyone in their small, sheltered community. Martin Beck, who has returned in a more senior position, struggles to find a replacement for the temporary head of the group, Steinar Hovland. But the Norwegian is becoming more and more interested in keeping his new role. The question is whether Martin can trust him?
