Milena Pojak, a Polish Au-Pair-girl dies after falling off a balcony at her host family’s house in Wiesbaden – apparently she got pushed. While inspectors Kerstin Klar and Christian Schubert interview the conservative catholic priest Pojak and the quiet host father Michael Keller, Bernd Reuther dives into the world of Au-Pairs. Talking to Liska, a friend of Milena leads Reuther and his team to interesting tracks among Milena’s friends and the Au-pair agency. A visit at the bar “5 till 12” harden Reuther’s impressions: Did the power of first love cause Milena’s death? Or did host mother Meike Keller risk Milena’s death by trying to salvage her broken family?
