The Traitors US Season 4: Cast, Twists & Peacock Premiere

The Traitors US has 23 celebrities competing against each other in a Scottish castle for a prize pool of $250,000. Faithfuls do missions to grow the fund and look for hidden Traitors who “murder” players every night and want to steal everything at the end. Alan Cumming hosts the game, and players vote at Roundtables to send suspects away. The game is a mix of strategy, deception, and chaos.

New Things in Season 4

There is a new Secret Traitor this season who chooses victims for the group to kill every night, and even other Traitors don’t know who they are. The first few episodes of Ardross Castle reveal shocking identities and surprises that make people even more paranoid. These sneaky mechanics change the format from previous Emmy-winning seasons.

A Cast Full of Stars

Some of the most famous contestants are Donna Kelce (NFL mom), Lisa Rinna (Real Housewives of Beverly Hills), Candiace Dillard Bassett (Real Housewives of Potomac), Rob Rausch (Love Island USA), Monét X Change (RuPaul’s Drag Race), Tara Lipinski (Olympic skater), Eric Nam (singer), and Ron Funches (comedian). The mix of athletes, reality stars, and entertainers leads to explosive fights.
