At first they thought Konrad's absentmindedness was due to his drinking. For years, he had been a benign parasite on the Koch family. But when their villa burns down because of Konrad's forgetfulness, Elvira Senn, matriarch of the Koch family, puts him on a strict regime. No longer allowed his daily tipple, Konrad recovers and even falls in love. But then his condition deteriorates, and Alzheimer's takes hold. As he loses his present, he regains his distant past, and this is what Elvira fears the most. As they wait for him to rewind to the crucial moment, his life is in danger from far more than a debilitating disease. At first, they put Konrad's absentmindedness down to an immoderate fondness for alcohol. For years he had been a benign parasite on the Koch family, first as the childhood playmate of Thomas, heir to the Koch family fortune, later as caretaker of the Koch family holiday villa on Corfu.
