This movie starts with a murder on a restaurant in Malmö. Martin Beck (Gösta Ekman) is sent down from Stockholm to investigate. They finds out that the murderer had escaped to Denmark but now is on his way back to Sweden. He is on a plane that will land in Bromma in Stockholm, so the police sends a car to pick him up. But on the way the policemen who is about to arrest the murderer stops on the way because of a kid who had said some stupid things to the cops. Because of that they dont get to the airport in time. That is maybe the most ridiculous thing i have ever seen in a movie and after that it is hard to take the rest of the movie serious. But Ekman, Lassgård and Bergqvist manages to keep the movie on an acceptable level.
