Claudia Winkleman greets a group of strangers as they arrive at a beautiful castle in the Scottish Highlands to play the ultimate prestige reality game of detection, back-stabbing and trust, all in the hope of winning up to £120,000. And it's not long before the players are questioning everything and everyone as Claudia secretly assigns the Traitors.Their task is simple. Under the cover of darkness, they must pick off their fellow players one by one, murdering them out of the game. The Faithful must try to work out who the Traitors are in their midst, banishing them from the game before becoming their next victim. The lucky ones who make it to the final have a chance of winning the life-changing cash prize. But if a Traitor remains, they'll steal all the money.
