With a chance to win up to £120,000 in this suspenseful psychological competition, Claudia Winkleman welcomes 22 strangers as they arrive at a stunning castle in the Scottish Highlands.
The Traitors, whose job it is to covertly murder a player every night without being discovered, are concealed among them.
The other players, called the Faithfuls, must make an effort to identify the traitors and exclude them from the game before they claim another victim.
Those who are fortunate enough to make it to the end have a chance to win that potentially life-changing sum of money. But if a Traitor remains undetected, they'll take all the money.
