The story takes place in Russia in the mid-1990s. In the summer, abnormal solar activity begins, making daytime deadly for humans. At night, hostile creatures—"Guests"—emerge from underground, mimicking human appearances. Through dialogue with various characters, who may be either human or hostile Guests, the protagonist gains clues about the visitor's danger, as well as information about the world beyond the shelter.
The hero receives information about new physical characteristics by which the Guest can be identified daily from radio and television news.
As the story unfolds, society outside the house collapses, and the government agency, the Committee for Emergency Situations (CES), begins forcibly taking guests away for "check-ups."
One day, the protagonist is informed that his neighbor was killed and his house was burned down.
The climax occurs when a pale guest and the murdered neighbor's daughter arrive at the door. The player's primary objective is to distinguish the real people from the disguised Guests. To do this, they must examine the guests for characteristic features: for example, perfect teeth, dirty nails, or bloodshot eyes. The process is complicated by the fact that none of these features definitively indicate the inhumanity of the guest: a human may possess similar characteristics, and the characters arriving at the house do not always agree to be examined. The subsequent events and the game's finale depend on the player's decisions. The game features 10 endings, determined by which guests survive and which are killed, whether the protagonist joins a faction (for example, a government agency or a doomsday cult), and whether they survive.

The Vigilante's origins remain largely unclear and underexplored. All that is known about him so far is his relationship with the Neighbor, who is his brother, and that he hails from another neighborhood, which he destroyed out of paranoia and hostility toward everyone he encounters, assuming the worst and considering everyone outsiders. He is very wary of discussions about his origins, as evidenced by his dialogue, and will do the same to the Protagonist without hesitation unless they prove they are not a "guest."

His name is Sergei, he is male, 35 cm tall (or about the height of a gingerbread man), and 42 years old. He is an elderly man, presumably older than his brother, Neighbor. He also has greasy, shoulder-length hair, dyed so black it appears blue. He wears a black cloak with the loops on each collar unfastened. Underneath the cloak, he wears a homemade collar made from fingers and ears, likely torn off from visitors or unlucky people. Underneath the first collar, he has another one, this one made from pearly white teeth. Underneath all this, he wears simple blue jeans. The vigilante also sports what appears to be a leather belt attached to a Romanian rifle, specifically a Pistol Mitralieră, a rifle similar to the Soviet AKM, with the grip connected to the wooden part closest to the barrel and a collapsible holster. He keeps a spare magazine in his left coat pocket, just under his arm. The vigilante is extremely powerful, driven by rage, hatred, and a cold heart. He will do anything to solve a visitor's problems, without regard for human life or the morality of his decisions. He will interrogate everyone he sees to clear the area of ​​visitors, and at the slightest hint of their presence, he will use his weapon. Initially, he thinks he's working in cooperation with FEMA and respects them to a certain extent, despite using more brutal methods to reach his conclusions. Eventually, he criticizes them for still having visitors, calling their work ineffective. Having finished checking the "Visitors" signs, he wastes no more time and moves on to the next visitor.
