Véra, disappointed by Didier, resigns from GEPAN and seeks answers from Zorel, the creator of the Cosmic Order, who claims to have met extraterrestrials. Didier and Marcel try to get their hands on a tape of the mysterious phenomenon filmed in Gondrecourt. Rémy must prove himself as an investigator with an unexpected case: a pond whose water has been transformed into a gigantic pile of shoes.

The missing witnesses resurface while Didier wonders about this unknown phenomenon which generates electromagnetic disturbances and influences the course of time. Véra and Rémy try to unravel the mystery of the shoe pond. The noose is tightening around Didier: if he wants to join Elise and work on the ARIANE aerospace project, he has one month to close GEPAN.
