Sergej in der Urne

Charismatic, erratic, egocentric, almost forgotten... Sergej Tschachotin was a scientist of international repute, friend to Pavlov and Einstein, revolutionary and pacifist. His private life was equally packed: five marriages, eight sons. It is the story of Tschachotin's epic existence - from 1883 to 1973 - through the memories of four of those sons. They speak of Tschachotin's role as a cancer researcher, his participation in anti-totalitarian propaganda movements, and his crusade against the arms race. Filmmaker Boris Hars-Tschachotin, Sergej's great-grandson, weaves together an intimate, tortured family saga that mirrors the myriad contradictions and possibilities of the 20th century.
