The Traitors is a psychological competition set in a historic castle in the Scottish Highlands, where contestants collaborate on various challenges to accumulate a prize pot. Secretly among the loyal contestants are the Traitors, whose objective is to covertly eliminate the loyal participants and seize the entire prize amount for themselves.
Under the veil of night, the Traitors execute their sinister plan, systematically eliminating loyal players. Meanwhile, the loyal contestants must identify and expel the Traitors to secure the prize. If the loyal group succeeds in identifying all the Traitors, they share the prize pot. However, if any Traitors remain at the end, they abscond with all the winnings.
