October 16th, 1984. Lépanges-sur-Vologne, France. Christine Villemin was in her home doing housework while her 4 year old son, Gregory, played in their yard. At some point she went to check on him but he was nowhere to be found. An anonymous call to Gregory's uncle revealed the terrible truth. The caller claimed to have taken the young boy and thrown him into the river. Hours later, little Gregory was recovered from the river. An investigation into the Villemin family revealed that harassing calls and letters went on for years prior to the murder. The caller was nicknamed "The Crow" after a controversial French film from 1943 titled, 'Le Corbeau'. Why did things escalate from harassment to murder? For decades, police and prosecutors worked to solve this crime. In 2017 a major announcement changed the direction of the case. Will the mystery finally be solved? Will Gregory's killers finally be brought to justice?
