[2] 22 strangers arrive at a castle in Spata as Pisti ('Faithful') contestants – hoping to share a prize fund worth up to €100,000.
Among them are the Prodotes ('Traitors') – a group of contestants selected by host Konstantinos Markoulakis on the first day, whose goal is to eliminate the Faithful and claim the prize for themselves.
Each night, the Traitors come together and decide upon one Faithful contestant to "murder" – and that person will leave the game immediately.

Greek actor and ANT1 personality Zeta Makripoulia was initially the frontrunner to host the program, although she later declined to focus on her theatre obligations instead.
