Senator Isaak Kohler shoots and kills Professor Winter in a crowded restaurant, while Winter is dining with the struggling idealistic young lawyer, Felix Spat. Kohler puts up no defense and is sentenced to twenty years. Kohler then gets his daughter Helene to pay the reluctant Spat to reinvestigate the case, on the assumption that Kohler is innocent. The newspapers pick up on this and begin to question whether Kohler was wrongly convicted.
