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.

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.
