Taeko is a charming grandmother who is 71 years old, yet active, youthful and her sexual desire does not decline. One day, I planned a family trip because I felt sorry for my grandson who was depressed because of a broken heart. On the surface, it was a traumatic trip, but the inner heart was a strategy to take advantage of the depressed grandchild and make it his own. Stealing the eyes of the son and his wife, the poisonous fangs of the lust genie approach his grandson.
