Imagine that there is a place on Earth that seems to be frozen in time. A place that can hide anyone who wants to escape from reality. Imagine that in order to get there, you just need to not look back and stay silent. There is only one problem: in such a place, sometimes things appear that are even more terrible than what you are hiding from.

The life of the Grozan family suddenly changes. They move to a new house, and fourteen-year-old Mark is forced to go to a new school. The boy is well-read, intelligent, but very shy and self-conscious - an ideal target for bullying. Every day, withdrawing more and more into himself, he dreams of a world where there is no bullying and no causeless cruelty. One day, Mark meets Sonya, a girl from a parallel class, who tells him about the existence of such a world and the possibility of getting there simply by using the lift in their building. The boy doesn't understand why Sonya is making up nonsense that can be easily refuted, but eventually follows her. He does not suspect that a simple trip to the tenth floor is fraught with something much worse than the destruction of his perceptions of the real world.
