On an early summer day in 2017, a mother reports that her 19-year-old daughter Tova is missing outside Hudiksvall. Despite a diligent search in every conceivable place, she has not been found. The girl's disappearance prompts a major police operation, but only after a few days is the case classified as murder when Tova's body is found, tied to a wheelbarrow that has been sunk in a lake. And now the hunt for the killer begins.

On the evening of April 21, 2021, the Jönköping police receive a call from a woman who wants to report that her husband, a business executive in his 50s, is missing and cannot be reached. The next day, his car is found burning on the outskirts of Jönköping and just a few hours later the man is found dead, hidden in the Dumme Mosse nature reserve a few miles from the car. The investigation has gone from disappearance to murder and for the police, the difficult work of finding out and finding who murdered the popular business executive is now underway.
