Based on the novel of the same name by Harry Turk. 1944. In occupied Poland, a railway line is being built to transport lead ore to Germany. The Valley of Seven Moons is restless, with construction materials disappearing and people vanishing. The occupiers feel uneasy on foreign soil. Despite increased security, partisans carry out one act of sabotage after another, hindering construction in every way possible. The German Rudek and the Jewish girl Martina, who at first stand aside from any struggle, join the partisan detachment.

Ella Conradi, a dedicated journalist from Germany, is in Jerusalem to report about the trial against the Nazi criminal Eichmann. Disgusted by the monstrosities that are revealed, she eventually returns to Germany. There, she wants to cover common cases and trials again. Her first assignment is a murder trial against a man called Ralf Jordan who constantly maintains his innocence. Conradi, who believes Jordan and wants to help him, starts to investigate the case - and thus opens up a political can of worms. The backgrounds of the case reach back to the Nazi period and involve officials of the Third Reich, who in the meantime have returned to their powerful positions.
