Original: Sanningen
A cold case turns topical again and turns everything upside down, intertwining the lives of several people.
Iris Broman leaves her old life in Stockholm and shifts to her half-sister's house near the sea in Ystad. She joins the Kalla Fall group in Malmö as the new manager. On the day Iris begins her job, a skull is discovered in the forest.
The probe into the disappearance of Benjamin continues; Iris and Jens successfully find new leads, despite Kerstin's refusal to keep pursuing the case.
Iris is becoming increasingly frustrated with the lack of progress in Stockholm. At work, her co-operation with Kerstin is faltering and she is also annoyed that she is not left alone at home. Iris wants to continue investigating Benjamin's disappearance despite Kerstin's protests.
Iris goes to Stockholm to identify a suspect in Christian's murder; Iris's former colleague Adam runs into trouble when she takes things too far and engages in the investigation; the Benjamin case is wrapped up and put on the shelf.
Iris is back in Malmö and continues the Benjamin case investigation; Iris gets into a fight with Kattis and goes to a hotel to be alone, but the memories of Christian haunt her.
Iris refuses to let go of the Benjamin case and suddenly various pieces fall into place; when Kattis helps Iris learn the truth about Christian, the sisters re-evaluate their relationship.
