1931. Hans Litten is one of the most celebrated lawyers in Berlin, famed for his brilliant mind and the rhetorical flair with which he defends those fighting back against the rapidly growing Nazi movement. So, when he calls Herr Hitler as star witness in the trial of a band of murderous SA men, the politician feels the full force of Litten's intellect, wit and courage. It arouses in Hitler a feeling he can't abide or forget. Two years later, on the night of the Reichstag fire, Litten is arrested. He is held without trial, beaten, tortured, and threatened as 'an enemy of human society'. As Litten disappears into the Nazi system, his indomitable mother, Irmgard, confronts his captors and, at enormous personal risk, fights to secure his release. This riveting drama explores her struggle, her son's resistance and the heroic battle of the weak against the powerful, truth against lies and mothers against murderers.
