Succumbing to the persuasion of a mysterious fellow traveler, three friends - Anton, Irina and Lipa - come to the Wheel of Fortune entertainment center. The institution looks like an old castle in which a quest takes place in medieval decorations. When the front door of the first location is tightly blocked, and the organizers stop responding, friends have only one way left - to follow the clues on strange maps and pass the tests, joining forces with other stuck players. But each next stage becomes more dangerous, the pictures on the maps change mystically, and terrible creatures roam in the quest rooms. It seems that at stake is not the victory in the game, but the lives of the players. What the hell is going on in this damn castle?
