Not only betrayal, but sex, grief and myriad other facets of human relationships are explored in this gripping drama from Kirill Serebrennikov. A man goes for a medical check-up, and the female doctor recognises him as the husband of her wife's lover. They attempt a revenge affair of their own, but events conspire against them. The story keeps twisting, but the shock revelations never get in the way of the convincing and profound characterisation. An elegant, powerful and alluring piece of pure cinema.
