The Wolf Girl(1974)

Overview:

Seeking vengeance, a man is directed by a sorcerer to cut his child out of his pregnant wife so he can create a miraculous 'ghost child'. Overhearing this conversation, his wife flees into the forest where she ends up giving birth to twins with the help of a kindly woman living there. Afraid her husband is chasing her, the wife flees further into the forest with just one of her children, but dies when she falls off a cliff after being chased by wolves. The wolves raise the child as one of their own, whilst her twin sister is raised by the kindly woman living in the forest.
