That's Not My Neighbor

These creatures are able to take the form of people and infiltrate their homes to kill and consume people's bodies. In order for the monster to unleash its brutal instincts, it needs to find itself in a confined space. So they chose the tactic of killing by infiltrating the apartments of their victims. Then in many apartment buildings there appeared the position of concierge-detective, who had to let in only real residents and their guests, but not monsters, who carry a special opsssnosti.
