Kirill lives in the capital. His apartment is taken over by a stranger. Friends, parents, colleagues and neighbors forget about him. The documents and keys to the apartment crumble into ashes. The hero is left completely alone.

Unable to solve his problem, Kirill sets out to wander around Moscow. Even his buddy, Kostya, who helped him, gradually stopped recognizing him. An unknown person calls on Kirill’s phone and dictates instructions to him. Following them, the hero comes to an inoperable water tower located near Moscow-3 station.

Once inside, Kirill sees 4 locked doors and a staircase to the second floor. There are 5 windows on the second floor. Each of them is located exactly where the door is on the first floor. After spending the night in the tower, the hero notices that the interior has changed.

One of the doors was now open. Behind it was another world. Every day, one of the remaining doors opens. Kirill receives a call from Kostya. Learning all about it, he comes to his friend, and together they set out to explore the world that has opened up.
