Participants come to a dark castle to fight for a cash prize. The entire team is divided into "Loyals" and "Traitors", who are selected by Malwina on the first day of the game. The main goal of the villains is to eliminate the other group and divide the reward among themselves. Every night, the Traitors meet for a joint debate to determine who from the Loyal group will be eliminated. All participants also take part in challenging missions.
