2006. Anita Sundström has only been with Chief Inspector Erik Moberg's Criminal Investigation Squad for a year when they have to tackle the aftermath of an armed robbery at a cash handling facility in Malmö. The raid has left one security guard dead and there is no sign of the stolen millions. Though the team make early progress, they soon become frustrated as the investigation stalls. Then a murder with a possible connection to the audacious heist only raises more questions than answers.

In the present day, Anita is just finding her feet as chief inspector. Her first big case is an old couple's apparent suicide pact, but if it is murder as she suspects, there seems to be no motive or suspects. Complicating her life further is the arrival of an FBI agent whose mission is to track down a Swede accused of a murder in Chicago.
