This sounds weird…par for the course in the world of Korean horror flicks.
“Summoned by an unexpected phone call, an elderly woman visits the country cottage she lived in as a child. Memories of a boy she knew 60 years ago come flooding back to her. Then young Suni and her family moved to a small village in Korea. There, they encounter a bedraggled orphan boy hiding under a bush and take him in out of pity. Called a “wolf boy” by some for his feral behavior and uncommon strength, Suni teaches the boy how to eat at a table, and read and write so that he might one day live among people. He repays her kindness with a devotion unequalled by any human being, a love that exceeds all normal expectations. Then one day a threat to Suni exposes the boy’s deadly bestial instincts, and in an instant he becomes the subject of the villagers’ fears. In order to save the boy’s life, Suni must abandon him while promising, “Wait for me. I’ll come back for you.”
