Za dobro djeteta

Maria Just works as a crime historian at the Police Museum in Copenhagen and is preparing an exhibition about a hundred years of unsolved murder cases when the brutal murder of the Secretary General of the Red Cross occurs, who is found with a mysterious sign carved into his stomach.

Investigators Mikael Dirk and Frederik Dahlin grope in the dark, but the case is engulfed in a lightning storm of media and the political top itself is involved. The management wants to see results with all its might - a challenge for two self-willed men who are working together for the first time and who are in many ways the exact opposite of each other. When Maria accidentally finds a connection between the current case and a half-century-old unsolved double murder in Hellerup, she inadvertently becomes embroiled in an investigation that leads to the most powerful people in the country and to a shameful chapter in Danish history.
