“Free State Midpoint” looks at a chapter of the National Socialist dictatorship about which far too little has become public from the perspective of those affected – eugenics. But the hermit Ernst Otto Karl Grassmé from South Holstein did bear witness to what happened to him, and what he would have liked for his life. In numerous letters, he wrote of what was done to him – even in post-war Germany, which denied him any compensation. On occasion with great humour, Grassmé fought for a life of dignity. And for 40 years he lived in the forest of the Horst Moors, far from the society that tried to take it from him. The film offers a unique and subjective perspective on the cruel practice of forced sterilization and its long-lasting effects … and asks the question of what constitutes a sovereign life.
