What could be hiding in school basements? Do you think all rubbish: broken desks, chairs without legs, armored beds? What if the school stands on the foundation of an ancient temple? Last bell, summer holidays are ahead. Kirill Oblomov and his friends are in a hurry to go to football, but the school director catches them and sends them to carry desks to the basement. Suddenly, under centuries-old debris, the guys find the entrance to an unknown tunnel. The temptation is great, the friends go downstairs and find a secret room with sarcophagi. One of the mummies holds in her bony hands something resembling a modern laptop. Kirill pulls it out of the brittle bandages, but the mummy suddenly comes to life. Only by miracle do the friends escape from the dark dungeon and that’s where it all begins. This laptop is nothing more than a guide to other worlds.
