The new investigation "Underground Business: who benefits?" will be released on REN TV on August 2.

Illegal races, illegal casinos and basement fight clubs – they earn billions from tickling their nerves! According to the Russian Chamber of Commerce and Industry, the volume of illegal gambling alone exceeds 300 billion rubles per year. REN TV journalists have found out from the inside how the underground entertainment industry works in Russia and who is behind it all.

Bloodied fighters, amid cheers from the crowd, mutilate each other in the backyard of a cottage in a horticultural association near St. Petersburg. In an exclusive interview, the organizer of these bloody fights will reveal why such "violent festivals" are in such demand and how much income they bring to the organizers.

Under the guise of adrenaline-thirsty newcomers, the journalists penetrated the closed world of underground racing on federal highways. What are the risks of the participants? How do the organizers hide from traffic police using secret signals? Why doesn't anyone check their driver's licenses before the start? And most importantly, who goes through a rigorous selection process, and who won't even be allowed near the track? The answers to these questions are given by the participants of the deadly races themselves.

Why do people voluntarily agree to be buried alive? What makes a "pain taster" dig his own grave? As part of the documentary project, the organizers provided an extreme blogger with a camera so that viewers could see the burial process literally from the inside. Who goes to gambling establishments banned in Russia? How do gamblers and underground casino owners find each other? Where are the roulette and poker tables set up and what kind of money is spinning there? The film will feature the revelations of a man who lost everything in an illegal gambling club.

The documentary "UNDERGROUND BUSINESS: WHO BENEFITS?" will be released on Saturday, August 2, at 17:00, on REN TV.
