1978. After a horrible failure, Didier Mathure, a brilliant space engineer, is transferred to head GEPAN, a unit specializing in UFOs. He is tasked with coming up with scientific explanations for the UFO sightings that are currently dominating the headlines. This is a nightmare job for an out-and-out rationalist like him, and he is determined to find a way out as soon as he can. But an extraordinary event unsettles his convictions and opens the doors to a world where anything is possible.
