Irene Wagner leads a comfortable and carefree life with her husband and two children. However, after eight years of marriage, dances, theater, opera and other social activities seem predictable and bland. Thus, more for fictional fantasy than by genuine desire, she begins a relationship with a young pianist.
The terror of being discovered by her husband and losing everything she has will plunge her into her worst nightmare. The ending is as surprising for the protagonist as also for the reader. The negative psychological effect produced by adultery and the value of marital and family love are very well reflected.
