Rookie cop Kurt Wallander stumbles into a hate crime in his own neighborhood. As he hunts the killer, the incident fuels anti-immigration anger.

Promoted to detective over his best friend, Reza, Kurt joins Hemberg on the case. Clues lead them to a notorious smuggler and a popular nightclub.

Kurt interviews illegal immigrants enrolled in a program funded by Gustav Munck, and soon finds a link between a pregnant refugee and the killer.

Hemberg orders Kurt to take some time off after the assassination of their chief suspect. The public considers the case closed but Kurt keeps probing.

Suspicious of Gustav's ties to the case, Kurt jeopardizes his romance with Mona by confronting the billionaire at a black-tie, Munck family affair.

Kurt, Rask and Hemberg try to connect their new suspect to a shipment of plastic explosive — and determine where and when the bomb will go off.
