OVNI(s)

Didier searches (unsuccessfully) for Claire and the cotton candy, hoping to reestablish contact with the aliens and understand their message. To delve into her childhood memories, Véra contacts a hypnotist, but unfortunately, in the presence of the doctor, Véra proves resistant to hypnosis - unlike Didier, who is inadvertently hypnotized!

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.

The GEPAN team must find a way to prevent Claire's experiment, which is scheduled to take place that very evening! In desperation, Didier asks Élise to help him save the world. Didier has one last idea: he wants to take advantage of François Duluc's appearance on a TV charity show to remotely activate the cotton candy and disable the particle accelerator, thus preventing a catastrophe.

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.

Several pilots and control towers around the world register hundreds of approaching UFOs on their radar, indicating a possible alien invasion. Claire tells Didier that she has been contacted by Delbrosse, his former enemy who has returned from the afterlife.

Everything is ready for the Inuit's journey to Tahiti. Didier and Marcel try to set a trap for Delbrosse to get her arrested, but they fail: she has already warned the police that there are 'illegal immigrants' at GEPAN!
