Since time immemorial, the vast Ukrainian forests have harbored countless secrets and unfathomable mysteries. They are home to wondrous mythical creatures dwelling among ancient trees, faithfully guarding their sacred realm.

Mavka is a Soul of the Forest and its newly chosen Guardian. Her primary mission is to protect the Forest and its sacrosanct Heart — the Source of Life itself — against any aggression or intrusion, including on the part of humans.

Lucas is an unassuming village boy, who has a great love of music and pours his talent into playing his wooden flute and dreaming of devoting his life to this passion of his. And Lucas’s music does help bring about something truly remarkable: Mavka and Lucas meet and fall in love. From the start, their union is pitted against formidable odds, but the obstacles loom even larger once the avaricious Kylina arrives on the scene claiming she’s a heiress to an old sawmill at the edge of the Forest and promising the villagers all the riches of the industrial progress she brought around from abroad. This serves as a façade to mask her true purpose: to get a hold of the Heart of the Forest (with the selfish purpose to stay young and beautiful forever) — the key to which is Mavka herself, who is already rendered vulnerable by her blossoming feelings for Lucas. To get to Mavka, Kylina wields Lucas as her weapon, and strikes anger and fear into the hearts of the villagers.

Will Mavka be able to save the forest? Will Lucas’s music be able to make miracles and save the love? Will the two worlds be able to unite against the evil?
