Everything that was left behind the scenes of the project. We reveal the secrets of filming in absolute darkness, how and where they designed a large building that did not let in a single ray of light, and some of the show's participants share their impressions of being in the dark and tell how they fought against their imaginations that drew them terrible monsters and nightmarish illusions.

When the lights go out unexpectedly, even for a couple of minutes, it already causes discomfort, and our participants will have to spend 42 hours in the dark. This time, Ilana Dyldina, Olga Sharypina, Alexander Novikov, Anya Kalashnik and Vyacheslav Chepurchenko will test their strength.

42 hours without contact with civilization. This time, comedian Alexey Krivenya, mixed martial arts world champion Valeria Karygina, rapper Eldar Dzharakhov, blogger Alexander Gridin and singer Tatyana Kotova will come face to face with their fears.

The new episode brought together the bravest and most passionate participants. This time, Lesha Yanger, Roman Volynsky, Anastasia Kraynova, Natalia Medvedeva and Kristina Zakharova will have to go through the trials in pitch darkness.

In the fifth episode of the show, not all participants will be able to withstand such a test, so at the very beginning there will be only two players left. But Sergey will still find something to surprise his bravest guests with.

The fourth episode brought together a very diverse female company. This time, Anastasia Volochkova, Ksenia Korneva, Anna Sedokova, Alana Mamaeva and Katya Golysheva plunged into the pitch darkness.

In this episode, almost all the participants are afraid of the dark, but Sergey Burunov does not consider this an excuse. They will still have to spend 42 hours without light. Anna Tsukanova-Kott, Alexey Stolyarov, Alena Shvidenkova, Valeria Lyubarskaya and Islam Rozubaev will test their nerves.

In this episode, the participants will have to come to terms not only with total darkness, but also with the difficult characters of their opponents. Zhenya Grishechkina, Magomed Murtazaliev, Mash Milash, Maxim Goncharov, Tatyana Morozova and Nadezhda Angarskaya will fight each other and their fears.

As a rule, a person receives most information through the organs of vision. But what if people are deprived of this opportunity? In the first episode of the show, Prokhor Shalyapin, Vladimir Marconi, Magomed Ismailov, Katya Adushkina and Anya Pokrov will try to live in a house completely devoid of light.
