Anna's brother lives a reclusive life in Greenland, and the older Alex has always been fascinated only by ice and solitude. After the death of their parents, Anna wants to bring him a painting, the only one from the family house on the Rebberg that Alex loved. While Anna searches for him in the Arctic with her thousand shades of white, all the family's secrets come to light, secrets of an almost normal German-Swiss family that lived by Lake Constance as if far removed from the passage of time. And yet wars and upheavals violently disrupted their lives. There is the story of the painter Otto Marquard, a friend who helped the persecuted escape and was himself arrested. The grandfather Josef, the "miracle doctor," who exaggerated the benefits of ice bathing. And not least the love marriage of Anna's German mother with the handsome Swiss Paul – which turned into a great, silent drama of alienation. While Anna recounts everything, the good and the bad times, the wounds and the pains, she also discovers the healing power of beauty and closeness that were always there despite everything. And she is able to piece together the shattered family portrait anew.
