"A Couple" is a film about a long term relationship between a man and a woman. The man is Leo Tolstoy. The woman is his wife, Sophia. They were married for 36 years, had 13 children, nine of whom survived. Each kept a diary. Although they lived together, in the same house, they wrote letters frequently to each other. Leo Tolstoy insisted that they read their diaries aloud to guests at dinner parties.
