As soon as they arrive in a mysterious mansion, the guests discover their identities during a secret ceremony. Will they be traitors or faithful? They must then work together in the first explosive mission.
The first faithful has already been murdered by the traitors under the cover of night. Guests must unmask the culprits, but some faithful provide a very comfortable smoke screen for the traitors.
While the traitors make a chain of murders, the faithful make a chain of errors; some are so convinced they have found the truth, they lead the group down false trails.
The good days seem to be behind the traitors who are beginning to attract suspicion; in a mission that does not fly high, some will be noticed for the wrong reasons.
The vice continues to tighten around traitors who are increasingly suspected by others; luckily, the mission creates doubts among the faithful who wrongly accuse themselves.
After betraying one of their own, the two remaining traitors are offered the choice to recruit a new ally among the faithful or to continue their murderous quest. The ghosts of the mansion come to haunt the guests during the mission.
The traitors finally seize the chance to recruit among the faithful. Who will be the guest to put on the cape of betrayal? On a day when the truth breaks out both at the mansion and at the mission, the recruit must learn to lie quickly.
The traitors must put 3 guests on the list of convicts. One of these guests is living his last day at the mansion since at the end of 24 hours, the victim will certainly be one of them.
Now that the three original traitors have been unmasked, the two newly recruited traitors find themselves alone in the conclave. How do they hide their new identities in a mansion where there are only six people left?
Now that they know the truth, the guests meet for a look back at the first season of the Traitors. Several lies have been told, many accusations have been made, wrong and right.
