Claudia Winkleman greets 22 strangers as they arrive at a beautiful castle in the Scottish Highlands to play the ultimate reality game of detection, backstabbing and trust, all with 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 from the game.

The other players form the Faithful and 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.

As the drama continues, the Traitors' second murder victim is revealed at breakfast. The mission leaves the players clutching at straws to find out more about their fellow players. Meanwhile, it might not just be the Traitors keeping secrets, as rumours circle the castle. As evening descends, will the Faithful band together to banish a Traitor, or will a fractious Round Table lead to the loss of another innocent Faithful?
