Carina Olsson provides the Malmo police information on drug deals comitted at her restaurant. She does this after being promised anonymity by the police. Two days later Carina is found shot. The execution is witnessed by Carina's seven-year old daughter Cleo. Cleo manages to escape and is hospitalized in a state off shock.
The murder happens on the outskirts of Ystad and is thus, assigned to Kurt Walander and his colleagues. With the connections to Malmo the Ystad police receives help from Frank Bork (Malmo Police). For PSI Stefan Lindman, who has already displayed signs of mental instability, working with Frank Bork leads to a round-trip to hell. Frank teaches Stefan what it means to stand up for your colleagues, no matter what.
