When a well-known gender theorist, and owner of Copenhagen's first gender-neutral preschool, is found murdered at a construction site in Malmö, Saga has to cooperate with a new Danish colleague, Hanne, who has difficulty accepting Saga.
The police receive a video demanding a ransom in exchange for Hans' release. They manage to locate him, but when they are about to free him, they find that his kidnapper has been shot and Hans has been abducted again.
Lillian discovers a wound in Hans' mouth, which turns out to be a branding mark. The other two victims are examined again and they also have the same kind of branding mark. The perpetrator is probably branding his victims, but for what?
An older couple is found murdered in a spectacular fashion in their house outside Ystad. They have a connection to a piece of art and they both have branding marks in their mouths, just like the previous victims.
