DAU. Three Days (2020)

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. He is a successful and prosperous scientist now, but feels excruciatingly dissatisfied with his family life. Through her he hopes to regain lost harmony and beauty, but reality intrudes when Nora, his wife, returns home.
