[1][2][3] The film tells about a girl named Olya, who spends her holidays with her grandmother and learns from her that a shishiga lives in their house.
Soon enough, Olya encounters one herself—a kind, gentle creature named Shishok (played by Rolan Bykov) who lives in her grandmother's home.
When the summer ends, Olya’s uncle plans to take her grandmother back to the city, but she ultimately decides to stay in the village.
Unaware of her choice, Shishok goes with Olya to the city, moving into her apartment and settling in closets and cabinets since there’s no attic.
On the last day of summer, they visit a park where they meet Brownie, who has come from Scotland for a symposium on unexplained phenomena.
