Having spent the whole evening in the company of a pretty girl, Ivan did not think that after they left the bar and caught the first car they came across, fate would take an unexpected turn. The fact is that the driver who took them home was not human. During the journey, the driver invites Ivan to play a game. According to the rules of the game, the driver will ask him a difficult riddle, and Ivan will have to guess it. And if he doesn’t guess it, then the price of losing will be the girl’s soul. Considering this condition as an unfunny joke, Ivan agrees.
