[8] In the series, Melvil Poupaud stars as a scientist tasked with leading a team of UFO researchers in France.

His career at rock bottom, Mathure is sidelined as the head of GEPAN, the agency's mysterious research department dedicated to the scientific study of unexplained aerial phenomena.

Supported by the department's eccentric staff, he must lead the search for evidence of paranormal and extraterrestrial life in France.

Alongside Véra, he travels through France in search of supernatural phenomena and seems more disconnected than ever from his children and his ex-wife, Élise, who has become director of CNES.

Together, they try to establish contact with intelligent life from elsewhere, watched closely by newcomer, Claire Carmignac, who handles communication for the Ministry of Development and Energy.
