The son-in-law found Ronald Ramm abused and killed in 1995. 26 years later, he is back in the house. For the first time, the public can join the inside, and see the crime scene. The son-in-law believes the unsolved murder is due to revenge - or predatory murder.

The person or persons who killed Ronald Ramm were probably looking for something in the house, the police believe. Per Angel, former forensic technician in Kripos, is back in the house, together with Jørn Lier Horst.
