In November 2019, children disappear in Winden. The police are baffled. There are missing persons posters on lampposts. Parents are beside themselves. There are school community meetings. The town is in turmoil.
First, Erik Obendorf goes missing. Then Mikkel, the youngest son of police officer Ulrich Nielsen, disappears. Finally, the deaf boy, Yasin. There is no trace of the children whatsoever.
