Berlin 1940. The city is paralyzed by fear. Otto and Anna Quangel are a working class couple living in a shabby apartment block trying, like everyone else, to stay out of trouble under Nazi rule. But when their only child is killed fighting at the front, their loss drives them to an extraordinary act of resistance. They start to drop anonymous postcards all over the city attacking Hitler and his regime. If caught, it means certain execution. Soon their campaign comes to the attention of the Gestapo inspector Escherich and a murderous game of cat-and-mouse begins. But the game serves only to strengthen Otto and Anna’s sense of purpose and a renewed love for each other. Slowly their drab lives and marriage are transformed as they unite in their quiet but profound rebellion...
