Series 4

An all-star cast of celebrities play the ultimate murder mystery game of deception. Hosted by award-winning actor Alan Cumming at an ancient castle in the Highlands of Scotland, they will work together on exhilarating missions to build a prize fund worth up to $250,000. But hidden amongst the Faithful contestants are the Traitors, whose goal is to eliminate the Faithful and claim the prize for themselves while remaining undetected.

Under the cover of darkness, the Traitors will murder the Faithful one by one and, alongside this treacherous spree, the players must try to uncover the Traitors and banish them from the game. If the Faithful contestants banish all the Traitors, they will share the prize fund, but if a Traitor makes it to the end, they will steal all the money.
