Mikhail Latyshev, the hero of Afghanistan, returns home after a concussion.
He falls in love with his former classmate Vera, who has a daughter, Aglaya. In a railway disaster, Vera and her daughter die.
Unable to cope with his grief, Mikhail turns to alcohol and becomes homeless.
One day, on a park bench, a stranger sits beside him and offers him brandy. When Mikhail comes to his senses, he finds himself in a secret laboratory where he is subjected to a horrific experiment—turning him into a reptiloid creature. The events unfold with frightening speed, affecting more and more civilians.
The FSB turns to specialists from the company “Zaslon,” who possess unique technologies.
Boris, one of “Zaslon’s” best employees, is sent to the Mongolian Shangrala—a mystical place shrouded in legends, where perhaps the answers to all questions are hidden.
Will he be able to unravel the mystery of the terrible Experiment? Can Mikhail regain his human form? And who is actually behind the nightmare events?
