In October 1945, the 19-year-old German prisoner of war, Mark Niebuhr [Sylvester Groth], arrives at a Warsaw train station with a group of captives. A Polish woman waiting for a train mistakes him for the SS officer who murdered her daughter in a raid on Lublin, and she is not alone in her suspicion. He is singled out, separated from the others, and locked in a solitary cell while a Polish officer presses him to write down his life story and reveal his real name. Mark insists on his innocence, claiming he is just a young man who does not understand why he has been detained or what is expected of him.
After four months in isolation, he is moved to a new cell that he shares with Polish criminals. As a German, he becomes a target of their anger and is subjected to constant harassment. He is assigned the harshest tasks, including breaking and removing stones from the rubble of bombed Warsaw. During a particularly grueling assignment, he manages to rescue a child, but in the process he breaks his arm. He is sent to a hospital, where the charge against him—murder—becomes the dominant thread of his new reality.
Once freed from the hospital, Mark is relocated to another facility where he shares a cramped cell with German prisoners of war. The group maintains a strict hierarchy, echoing the military order they once upheld. They are led by General Eisensteck [Fred Düren] and Major Lundenbroich [Klaus Piontek], two men who still cling to fascist ideals. As Mark begins to learn more about his fellow prisoners, he comes to an unsettling realization: though each of them professes innocence, many of them are actual murderers and war criminals. The atmosphere shifts as Mark slowly distances himself from his cellmates, confronting a sobering truth about the war and the ordinary Germans who fought in it.
The tension escalates as the men who once commanded their own cells are gradually executed, one by one, and the truth of their crimes begins to surface. In the midst of this, the Polish authorities examine Mark’s story and, after a careful assessment, come to a surprising conclusion: they believe him. In a twist of fate, Mark Niebuhr is released, leaving him to reckon with the heavy weight of guilt and responsibility in a postwar landscape that has already begun to forget the faces of those who fought and the costs they paid. In a story that hinges on memory, identity, and accountability, the film quietly questions what it means to be innocent when one’s country has committed acts that demand reckoning.
Overall, the film uses Mark Niebuhr’s journey to explore the murky line between justice and vengeance, the enduring impact of fascist ideology, and the complicated path toward truth in the aftermath of war, inviting viewers to reflect on how easily individuals can be drawn into a system built on violence, obedience, and fear. Mark Niebuhr [Sylvester Groth] remains at the center of that reflection, a figure whose personal narrative forces a hard examination of what guilt and responsibility truly mean in a world reshaped by conflict.
