There are mysterious and terrible rumors in the city about some kind of black mark that suddenly appears on the palms of a variety of people. But the circle of rich people in the city knows nothing about these rumors. They are busy with a mysterious game that has appeared in their city from nowhere. Gamers who complete all stages of the game can make a fortune for themselves - the game's prize fund is $6 million, and no one has ever won this money, so each of the participants has a chance. No one knows why the game is played in a dungeon. Nobody knows about transformers from the human body, the invention of a scientist unrecognized by the world. Nobody knows what the meaning of the game is and how it is connected with underground criminal battles without rules - but, nevertheless, a variety of people strive to get into it. People who dream of finding adrenaline and money, but find horror and death.
