1914: Young Anton Heideck has arrived in Vienna, eager to make his name as a journalist. While working part-time as a private tutor, he encounters Delphine, a woman who mixes startling candour with deep reserve. Entranced by the light of first love, Anton feels himself blessed. Until his country declares war on hers.

1927: For Lena, life with a drunken mother in a small town has been impoverished and cold. She is convinced she can amount to nothing until a young lawyer, Rudolf Plischke, spirits her away to Vienna. But the capital proves unforgiving. Lena leaves her metropolitan dream behind to take a menial job at the snow-bound sanatorium, the Schloss Seeblick.

1933: Still struggling to come terms with the loss of so many friends on the Eastern Front, Anton, now an established writer, is commissioned by a magazine to visit the mysterious Schloss Seeblick. In this place of healing, on the banks of a silvery lake, where the depths of human suffering and the chances of redemption are explored, two people will see each other as if for the first time.
