Twenty of America's most cunning contestants, a mix of famous faces and everyday Americans, play the ultimate murder mystery game. Hosted by award-winning actor Alan Cumming at an ancient castle in 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. Under the cover of darkness, the Traitors will murder the Faithful one by one in a treacherous spree while the players 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.

With a place in the final on the line, the players must risk everything for a shot at victory; gambles are made at the roundtable and the Traitors face a mission where one wrong move could prove fatal.

Game-changing evidence comes to light at a critical roundtable, giving the players one last chance to identify a Traitor; an explosive daredevil mission could sway the prize pot and a calculated murder leaves just six standing.

Lies are exposed and friendships unravel as a betrayal threatens to change the game; with the final five gathered at the fire of truth, Traitors and Faithful alike scramble to seize control in a desperate bid to claim the life-changing prize.
