Kurt Wallander and the other police officers try to find the connection between a horrible murder that took place in Ystad and the kidnapping of one of the police force's daughters. It also seems someone has infiltrated the police and controls every move the police make.
Unfortunately the movie Wallander: Mastermind is not yet available on HBO Max.
