Didier and Véra present their findings on the cotton candy to Fontmichel and explain to him that they may be able to communicate with the aliens. But Claire Carmignac, an advisor to the Ministry of Energy, who considers Didier a failed scientist, has no time for his crazy theories and refuses to let him continue his experiments at the power plant. Meanwhile, Fontmichel has removed the cotton candy, fearing that it will delay the opening of his power plant.

Didier tries to understand why contact with the aliens has been lost. A group of UFO enthusiasts demand Didier's reinstatement and the truth about the cotton candy in front of the CNES headquarters. Élise is so angry that Didier is encouraging the protesters under her windows that she reveals a secret that Diane had shared with her: Didier was on LSD when he saw the UFO in Larzac.
