The body of old Theodor Reifenrath is found in Mammolshain in the Taunus. Accident or Murder? Because the safe is open and empty, inspectors Pia Sander and Oliver von Bodenstein start investigations. In the dog kennel in front of the house, they make a horrifying discovery. Alongside to a nearly starved dog, she finds human bones in the ground. Three women's bodies are recovered by the forensic experts. But who are the murdered women? The dead man and his deceased wife Rita had used the large house by the lake as a kind of children's home and had raised many foster children here over the years. However, the two were not loving foster parents. Rita has been missing for many years. Probably suicide, but her body was never found. The investigators are concentrating on the foster children, who are now all grown up and in the middle of life. The pattern of killings is striking: Apparently the perpetrator always kills on Mother's Day. And that day is near.

The Volga is a myth, a unique river of superlatives and the natural lifeline of Russia. With a length of more than 3,500 kilometers, it is the most powerful and water-rich river in Europe. Their catchment area is larger than France, Spain and Portugal combined. While all the other great rivers on earth flow into an ocean, the Volga fills its own sea, the largest inland lake on earth, the Caspian Sea. On the way there it flows through rustic forest areas, through wide steppes and dry semi-deserts, each of which is home to a unique wildlife. In three years of filming and on countless expeditions, the Altayfilm team and their Russian colleagues managed to capture the fascinating stream in grandiose pictures and to fully portray it for the first time. Opulent pictures and breathtaking aerial photographs alternate with animal behavior that has rarely been documented before, told with fine humor and a special lightness.
