Annyeong, Hyeonga plot
9-year-old Han-yi's older brother has a dangerous brain tumor discovered. Han-yi does everything he can to cheer up his brother in the hospital. One day he goes with his friend Wook-yi to his native village in the province. Wook-yi wants to show Han-yi 'Tarzan', a feral loner living in the mountains. The pair are so startled by Tarzan's sudden appearance that a fall knocks Wook-yi out. Tarzan manages to get Wook-yi back on his feet by means of water. Han-yi now knows for sure that this is "the water of life", and takes the water home to heal his brother.
