Synopsis
Many frightening and incomprehensible threats surround a survivor in Moscow in 2033: they scowl from the impenetrable darkness of the underground tunnels or wait in the jungles of the new world's ruins. But among the hundreds of chilling tales of stalkers, which are so fond of telling around evening fires, there is one. A special one. About a horrific monster that lives in the waters of the Yauza River. They say that when the monster becomes hungry, it chooses a victim and sends him a call that no one else can hear. And from then on, the wretched man is doomed. He will have no rest until he finds his way to the cold, murky waters of the river...
