The Traitors is a psychological game of treachery and deceit taking place at an ancient castle set deep in the Scottish Highlands. Contestants work together on a series of missions to build a prize fund. However, hidden amongst the Faithful are the Traitors, whose goal is to eliminate the Faithful and claim the prize for themselves.

Under the cover of darkness, the Traitors murder the Faithful one by one in a treacherous spree, while the Faithful 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 (or Traitors) makes it to the end, they will steal all the money.
