One evening in March 2017, the police in Örebro received a call from a woman in the purple community Ställdalen who said she had killed her roommate when he tried to rape her in the shower. The police quickly arrive at the crime scene, but once there you sense that something is not right and what starts out as a seemingly straight and simple matter quickly develops into a complicated murder case.

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.
