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 threatens the Heart of the Forest. 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?
