On a hot June day the body of a sixteen-year-old girl washes up on a river bank outside of Frankfurt. She has been brutally murdered, but no one comes forward with any information as to her identity. Even weeks later, the local police have not been able to find out who she is. Then a new case comes in: A popular TV reporter is attacked, raped, and locked in the trunk of her own car. She survives, barely, and is able to supply certain hints to the police, having to do with her recent investigations into a child welfare organization and the potential uncovering of a child pornography ring with members from the highest echelon of society. As the two cases collide, Inspectors Pia Kirchhoff and Oliver von Bodenstein dig deep into the past and underneath the veneer of bourgeois society to come up against a terrible secret that is about to impact their personal lives as well.
