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.

Claudia reveals who has been murdered during the night by the traitors. As the players head to the round table for the first dramatic banishment, will the faithful be able to catch a traitor?

There are tears and anger over the breakfast table as the identity of the second person to be murdered by the traitors is revealed.

The players are given the chance to add a potential £10,000 to the already growing prize pot, and with a tense round table on the horizon, one player has an extremely difficult decision to make.

With the traitors set to murder again, the faithful are even more determined to catch a traitor in the act.

The players focus on building the prize pot in a mission that sees them sink to new depths of despair. But that’s the least of their worries, with an explosive round table on the horizon.
