1165. Stonemasons are murdered and panic spread. Some people see these crimes as the devil's hand. Others suspect the followers of this new sect who claim to be the True Christians and will soon be called the Cathars. The Archbishop of Narbonne sends a young nobleman to conduct the investigation, the Cathars intend to do everything to exonerate themselves and the victims' companions are ready to do anything to avenge them. Three investigations for one truth.
