Lokis, a Manuscript of Professor Wittembach (1970)

Lokis: Rękopis profesora Wittembacha

A pastor studying folklore in remote parts of 19th century Lithuania is invited to stay with a young nobleman. His mother is sequestered and mad. It seems she has been attacked by a bear as a young wife and local peasants whisper the young man may be the son of a bear. A doctor, who treats the mother with old-fashioned remedies, reveals this to the pastor. Young nobleman's wife is found with a bite and the man has disappeared into the woods.
