In the small village of Krasny Kamen, three seventh‑graders — Roma, Asya, and Gordey — are enjoying a carefree summer vacation. But one day, while swimming in a flooded copper‑ore quarry, Roma discovers a magical malachite nugget that grants him an extraordinary ability: everything he draws becomes real. However, along with this wondrous find, an ancient spirit of the old mine — the Black Raven — is released from the depths of the quarry. He truly can fulfill absolutely any wish, but in return he demands a price far too high. Now the friends must show strength of character and prove that pure intentions, warmth of heart, and genuine, steadfast friendship can stand against a terrifying ancient evil.
