On a gloomy November day, construction workers discover a human skeleton at the abandoned airfield of the US Army in Eschborn. Shortly thereafter, a woman is pushed off a bridge onto the street. The investigations lead Pia Kirchhoff and Oliver von Bodenstein into the past: Many years ago, two girls disappeared in the small Taunus village of Altenhain. A circumstantial evidence trial put the alleged perpetrator behind bars. Now he has returned to his hometown. When another girl goes missing, a witch hunt begins in the village.
