In the Alps, 28 people mysteriously disappeared between 2007 and 2017. A sad unexplained record for the region. This is the story of one of the greatest failing of the French judicial system.
Maëlys, 8, disappears during a wedding. Her remains are found six months later. Nordahl Lelandais, one of the guests at the party, faced with overwhelming evidence, confesses to the crime. From that moment on, the cops wonder whether the suspect may be involved in other disappearances in the area. Their intuition will prove correct when they discover that, a few months before Maëlys' disappearance, a young 24-year-old Army corporal also fell prey to this man, without arousing the slightest suspicion.
In France, serial killers are considered a fantasy, a legend straight out of an American movie. This may explain why justice has not sought links between these different cases. This film reveals the disorderly personality of Nordahl Lelandais, someone who could be "the French serial killer".
