Die Chefin S03E03 - Kinder

A woman of unknown origin and identity is found dead near the Munich train station with a crying baby in her arms. A short time later, the parents Insa and Peter Wilde are there and relieved to hug their stolen son. Vera Lanz and her team now have to solve the murder of the dead woman. Again and again they come across questions as to the motives for kidnapping the child, since the woman did not demand a ransom from the wealthy Wilde couple. When Vera finally finds out that the woman was illegally smuggled to Munich and that the baby is a child from Eastern Europe that was adopted through an agency, she seems to be getting closer to solving the case.
But then suddenly Vera's daughter Zoe is kidnapped and Vera is confronted with the reference to officials of the Russian mafia. What role does the mediation agency Seerosen play? What was the Wilde couple willing to do to have their own child? How is Vera supposed to investigate further without putting her daughter in danger?
