The Willak family has already been living and conducting research on Luna, the terrestrial moon. In 2100, they fly to Earth to obtain the legal status as persons for their new family members, the androids.

Therefore, a deadly power battle takes place on the moon and on the Earth, which ultimately turns out in favour of those who concede the status of legal entities to the androids.
