Véra wants to use her mind to help the aliens prevent the impending catastrophe, while Didier, who takes a more practical approach, tries to find the star that is about to explode. So he takes advantage of a visit to his daughter Diane's university to explore the library's extensive astronomy section.

He tells her the story of the tribe that was teleported from its homeland of Siberia to a doomed planet after encountering mysterious 'moon men' with supernatural powers, who the shaman says are floating, human-like aliens. Before helping the Inuit return to Siberia, Didier wants to prove that they lived on an exoplanet.
