In the fall of 2018, the giant building of the Khovrin abandoned Hospital, which had been empty for almost forty years, was demolished in Moscow. The abbreviation XZB was familiar to all stalkers in the capital. The huge abandonment attracted not only them, but also marginals and teenagers — all those who cannot find a place in life. Without the flow of information pouring from every telegram channel, without the stories of distant acquaintances and local celebrities replacing each other, without an avalanche of updates and spam, Yuzhin felt a cavity forming in his surprisingly empty head and filling with thoughts by itself. Sharp, frightening, hopeless thoughts that are so easy to hide from just by opening the news feed. On the eve of the demolition, four people come to the KHZB: blogger Yuzhin, spoiled by attention and money, aspiring cameraman Taras and assistant director Kira, and Kostya, the guide to the abandoned building. They're shooting a video together, although the reasons they're here are different. Someone needs money, someone needs the truth about their own past, someone needs views. But if HZB let them in, then for some reason. But why? And will he release it?The hospital is a land of wonders, he went into it and disappeared there.
