Germany, 1943. Lilly Wust is in her late twenties, married, mother of four children. Her husband is a soldier in the war. One day, Lilly meets the self-confident Felice. The two become friends, but Lilly senses from the start that Felice wants more from her than mere “friendship”. At first, Lilly reacts dismissively to Felice’s courtship. Eventually, however, a passionate love develops between the two women.

Even when Lilly, who is married to a convinced Nazi, learns that Felice is Jewish and belongs to a resistance group, she stands by her lover. She divorces her husband and takes Felice into her apartment. For as long as possible, the two women repress the brutal German reality of life at that time and all the impending dangers. Until the Gestapo shows up at their apartment in August 1944.

For one of them, this forbidden love becomes the decisive experience of her life. For her friend, an intrepidly flamboyant Jewish woman working for an underground organization, it is a game of fire – but also her last chance to wrest a fulfilled piece of life from the murderous regime.
