A psychological drama exploring the notion of the doctor as a moral authority, who within the framework of their everyday work must face questions of life and death. The film is adapted from a novel by Valja Stýblová, in which the author draws upon her personal experiences as a former neurosurgeon. The protagonist of this drama is an ageing professor, based at a Prague neurological clinic, who is haunted by issues concerning his own principles and values, and also by the case of a young patient, Víťa, afflicted with an inoperable tumour.
