After the Alpine case, Sheriff Nieman (Jean Reno) was promoted to police chief based on his outstanding case-handling skills. He found a body buried in the walls of the Rabodi Monastery. The mysterious symbols carved around the deceased and the strange rites on the deceased seemed to hide unusual meanings. When young police sergeant Leda (Benoît Magimel) discovered and rescued a half-dead man resembling Jesus by the church, he thought he had only met a religious fanatic, but soon discovered that there was a close connection between this incident and the case Nimans was responsible for. Nimans and Leda were shrouded in fog until they finally discovered that each of the victims had the same name and profession as the twelve apostles of Christ. Mary (Camille Natta), a female police officer and religious historian expert, helps Nimans and Leda try to expose the truth of this incredible conspiracy. Niemen and Leda are determined to find the answers to all their questions, but to do so they must take a deep risk to discover a secret that has been buried for centuries...
