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.

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.

As the ultimate psychological reality show continues, and the number of players keeps on dwindling, another of the faithful does not make it to breakfast - but who has been murdered?

It is the penultimate day of the game, and for the players left in the competition it is a race to the final, as everyone considers their survival.

In the biggest mission yet, the finalists are given a last chance to add more money to the overall jaw-dropping prize pot. But who will be victorious?
