It is 1961 and the rural Dutch province of Overijssel is quiet. Bomb craters have been filled, buildings reconstructed, and the war is truly over. Living alone in her late mother's country home, Isabel knows her life is as it should be: led by routine and discipline.

But all is upended when her brother Louis brings his graceless new girlfriend Eva, leaving her at Isabel's doorstep as a guest, to stay for the season.
In response, Isabel develops a fury-fueled obsession, and when things start disappearing around the house--a spoon, a knife, a bowl--Isabel's suspicions begin to spiral.

In the sweltering peak of summer, Isabel's paranoia gives way to infatuation, leading to a discovery that unravels all Isabel has ever known. The war might not be well and truly over after all, and neither Eva, nor the house in which they live, are what they seem.
