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.

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.

One of the faithful is keeping a huge secret from the group, but a dramatic confession at the round table changes the game.

The faithful nervously wait to see who the traitors murdered overnight. After another mission to increase the prize pot, Claudia throws a huge twist into the game.

The previous night has left the players with more than just a hangover. With one player already regretting their actions, and relationships tested, accusations soon start to fly.
