Peacock's latest reality series, The Traitors, will see betrayals like never before as 20 devious contestants enter an intense new psychological competition. The first trailer for the series shows the large cast — which includes 10 well-known reality stars — competing for a quarter of a million dollars.

They'll also be able to "murder" some of the "faithful" (i.e. innocent players), which eliminates them from the competition and increases the chance a a Traitor will win it all.
