Boanthropy

Mikhail Fagotov is a veterinarian on a cow farm.
During a standard check, he discovers a strange cows pathology — a purple shade of the eyes.
Assuming that it may be a new virus, he asks the boss to quarantine the farm and continue the research.
The head of the farm refuses.
Fagotov tries to solve the problem on his own, which leads to irreversible psychophysiological changes.
