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.
