Alienated from the rest of the scientific Institute in which they live, a lonely housewife and her teenage son break the ultimate taboo, with only their submissive maid to bear witness.

It is 1956. Dau is a distinguished Soviet scientist who meets up with the love of his youth – Maria, a Greek actress – during her three day visit to Moscow. They haven’t seen each other for 25 years. Dau is a successful and prosperous scientist, but feels excruciatingly dissatisfied with his family life. Through Maria he hopes to regain lost harmony and beauty, but reality intrudes when Nora, Dau’s wife, returns home.
