John O'Neill, a school teacher, has something in mind. That is, to spend the Christmas holidays alone. He will reject invitations from his family and from work and absolutely enjoy being alone! But just before Christmas, he receives a present from his grandfather. When he opens the large package, inside is a self-proclaimed humanoid housekeeper robot. A suspicious robot (temporary) and a young man who stubbornly wants to be alone... The two begin a mysterious life together.
