Sasha's best friend is the horse Jonathan. Only he can share with a 13-year-old girl her joys, losses and hopes. Neither his classmates nor his mother understand Sasha. In her opinion, the obstinate horse, which reminds the girl of her father, is a burden for the family. And only the girl’s grandmother is ready to do any kind of recklessness to support Sasha in her quest to save the horse. To achieve this, the young athlete and Jonathan have a long way to go, leading to great victories and new discoveries.
