Inspector Wallander and his team investigate a murder and an unexplained death. They arrest 18 year old Sonja Hokberg after they find a taxi driver stabbed to death in his car. Sonja is found covered in blood and freely admits to the killing, though she provides little additional information. In the second case, the police find a dead man on the street who was apparently using the ATM. He is Denis Falk and the police learn that he had just recently been given a clean bill of health after a thorough medical exam. When Sonja escapes from her jail cell and Falk's body is stolen from a mortuary, the police discover a link between the two. When they find Falk's computers running a mysterious program however, they find they are dealing with a terrorist plot. Wallander's social life takes a positive turn when his daughter Linda signs him up at a dating service and he gets a call from an attractive divorcée. Could this be the start of a new life?
- In the town of Ystad, police inspector Wallander has two deaths to investigate that seem entirely unconnected: a taxi driver who has been brutally beaten by two teenage girls and later dies, and a computer consultant who has dropped dead in front of a cash machine. But soon enough mysterious and grisly events begin taking place. Events linked to something much more sinister that might be threatening the entire global finance market.
