In a world where ancient Slavic beliefs and modern life intertwine, a young medical student named Gosia reluctantly travels to a rural village in Poland to complete her medical internship under the guidance of a traditional healer, or "szeptucha." Skeptical of the old ways, Gosia finds herself drawn into a realm of folklore, magic, and mysterious occurrences that challenge her scientific understanding. As she navigates the complexities of village life and her own evolving beliefs, Gosia encounters mythical creatures and uncovers secrets that force her to confront her own identity and the power of ancient traditions.
