The Snake Woman (1969)

An aged snake turns to a beautiful woman after the devil's order, and tempts a young Buddhist monk. The two marries, and gives birth to a son. The snake tries to kill her husband to obey the devil's order, but she can't because of the love she built with the man. The devil turns the snake into a stone. But with the help of a Buddha, she turns back to a human, living happily after with the monk.
