The Man in the Glass Booth (1975)

Arthur Goldman is a wealthy Jewish land developer in Manhattan, he who is supported by his loyal Jewish personal secretary Charlie Cohn, and his black assistant Jack. Despite his wealth affording him all the comforts and luxuries, not all is well in his life. Widowed, he yearns for the physical and visual aspects of a female companion. A Holocaust survivor, he is haunted by visions of his past, including of his father who was killed in the concentration camp where they were housed, and of Karl Adolf Dorff, the camp kommandant who he holds responsible for his father's death. What no one knows is that he has mementos of sorts of the Holocaust hidden away in a locked room in his apartment. He also believes "people" are after him. These delusions have led to him being under medical care. However, the delusion that people are after him is not a delusion as Mossad agents storm his apartment, and whisk him away to Israel to stand trial for war crimes in their claims that he is really Dorff, they confirming such with medical evidence before arresting him. While Goldman/Dorff does not deny being who they claim him to be when they have him in custody, he, planning on representing himself at the trial, nonetheless believes he will prove himself not guilty by telling the truth under that oath of truth at a trial.
