The dead couple Olof and Carolina Wachman are found murdered in their magnificent estate. The investigation finds that she has been tortured and raped in front of her husband before they were both killed. A death that must have been a relief after the torture they both went through.

Kurt Wallanders daughter Linda and DI Stefan Lindman now have to show that they are as good a pair of investigators as Kurt Wallander himself.

Slowly but surely we see that the murder is about revenge, a revenge that can be traced back 20 years.

Kurt and his men tries to find the connection between a horrible murder taken place in Ystad and the kidnapping of the daugher of a memeber of the police force. It also seems someone has infiltrated the police and controls every move the police make.

An explosion in one of Ystad's power grids shuts down the electricity in the whole city. Wallander (Krister Henriksson), who is in the middle of a crayfish party at his newly bought house with his colleagues, are called in in the middle of the night. At the same time, the municipal commissioner of Ystad, who has just approved and inaugurated an exhibition showing pictures of Muhammed, the muslim prophet, at the city hall, is being murdered in his house. With less policemen than usual due to various reasons, Wallander and his men are having a hard time taking care of both cases. It gets even worse when several cars placed on various roads outside Ystad explodes, the security service (SäPo) are asking questions, and the police commisioner calles in the army to keep Ystad safe. As to make things even more complicated for Wallander's (From IMDB)

A motorcycle rider is found murdered by the police, and the trail leads them to a local MC Club. The Club uses other riders to smuggle drugs across the Öresund bridge. Wallander believes that players outside of the MC club are trying to claim the local drug market when all clues indicate that the victim was one of the couriers. Only when Wallander's colleague Isabel gets violently assaulted in her home does he understand the lengths they will go to to achieve their goal.
