End of Innocence is a two-part television film that focuses on the work of the German Uranium Association during World War II.

At Farm Hall in England, the ten German nuclear scientists interned there as part of Operation Epsilon learn of the dropping of the first atomic bomb on Hiroshima in August 1945. In flashbacks, the development of the German uranium project is recapitulated chronologically from the discovery of nuclear fission by Otto Hahn to the work of Kurt Diebner at the Heereswaffenamt to the experiments of the Kaiser Wilhelm Institute for Physics under Werner Heisenberg and Carl Friedrich von Weizsäcker at the Haigerloch research reactor in spring 1945.

In the fall of 1945, nineteen year-old Mark Niebuhr, is accused of murder and is jailed as a prisoner of war in Warsaw, Poland. He maintains his claim of innocence throughout long periods of solitary confinement. When Mark is placed among a group of Polish criminals, he becomes the target of their aggression. Later, Mark experiences true hell in a communal cell with fanatical German war criminals. Turning Point is based on actual events from Hermann Kant's novel of the same name.
