Country of origin: Unknown.
Date: Maybe the 80s or older.
The ruler of a castle steals the soul (?) of a female singer and puts it in a box (?), in order to force her to sing only for him.
His life is tied to an old tree standing near the castle. If the last branch of the tree breaks, he dies.
The tree is rumored to be surrounded by monsters and ghosts.
Nearby villagers eventually rescue the woman. Maybe somebody shoots the last branch off of the tree.
They also discover that the monsters were fake.
