Дед, Василий и Квадрат

Author's family history. We can say that this is a movie about my grandfather. It can be said that he is about a horse and about the relationship between a man and a horse. And you can do it like this: how the horse influenced the history of the country and the world. And everything will be true, because my grandfather Zavilgelsky Boris Dmitrievich was the director of the First Moscow Stud Farm, where the legendary stallion Kvadrat was born and the equally legendary groom Uncle Vasya worked.
