Ernst never got to see his father, who died in the shelling of the Shell House during the Second World War. But the question is whether his father or mother have had other children who can inherit Ernst, now that he has died without having started a family himself. Host Mette Frisk and archivist Adam Jon Kronegh go in search of Ernst's heirs.

When Boris dies, he leaves a will which states that his Russian family will inherit him. Boris's mother originates from Siberia, but in the National Archives there is no immediate trace of the Russian family. Until suddenly there is a connection to a high-ranking man in Russia.
