'The Traitors' Season 3: Meet the 21 Reality Stars Set to Visit Alan Cumming's Scottish Castle

It's the most wonderful time of the year: When a group of reality stars descend on a castle in Scotland to kill each other for money. No, it's not The Hunger Games; it's the star of filming on the third season of reality juggernaut, The Traitors, and it's one of the best things you probably haven't seen. Yes, yes, I realize we're all Anglophiles and therefore above such pedestrian, potentially tawdry entertainment as "reality television." But The Traitors is a genuine phenomenon, and with good reason: It's great.

The series is hosted by Masterpiece Mystery's own Alan Cumming, donning a variety of colorful and over-the-top outfits as he embraces his purring, secretive persona as the Scottish host with the literal most. Part narrator, part mediator, and part outright enabler, Cumming embraces the role of The Traitors host as though he were playing a Bond villain, and the end result is one of the most popular reality hits in years.

The premise of The Traitors will be familiar to anyone who ever played any version of Assassin (or Mafia or Werewolves) while away at college. Of the series' twenty-some cast members, a few are assigned to play the roles of "Traitors," who must work together to eliminate the majority, a.k.a. the "Faithfuls." The Faithfuls know that Traitors are among them, but they don't know their identities and must spend the season attempting to discover their secrets even as they compete alongside them in group missions.
