Criminologist Fredrika Bergman joins a police unit led by celebrated detective Alex Recht. The team resent her presence, but need her help in a mysterious child abduction case with few suspects.
Tragedy strikes, another child goes missing and Fredrika, Alex and the others have a race against time to find the serial offender before any more children are harmed
A priest and his wife, who work with refugees, are murdered in their home and a series of robberies is linked to the murders, but how and why? Meanwhile, Alex's marriage is in trouble.
The murdered priest's daughters could be under threat from a radical organisation. Meanwhile, Fredrika gets a job offer from Aina and Peder takes one risk too many.
Two Jewish boys are kidnapped on their way to tennis practice. Their school insists it's a hate crime but Fredrika and Alex aren't convinced as they see hostility between the families.
Information indicates that the kidnapping and its consequences are family related, not hate crimes, and it seems that a fearsome old Jewish legend 'The Paper Boy' is coming to life
The body of a woman, who had been missing for three years, is found. The investigation churns up unwanted emotions for Alex who worked the original case, and new finds only muddy the waters.
Fredrika's private life is dragged into the investigation when Spencer is implicated. Meanwhile, Peder's brother sees more than he should and takes off, and developments in the case prove fatal.
A man who got off a murder charge is found dead in his own home. Before long, another person who seemed to have evaded justice is killed, while Fredrika's private world suddenly collapses.
Peder tries to get back on the investigation team as the body count mounts but he is not accepted any more. A dangerous killer is at large: could an insider be involved?
