What does it feel like to wake up with streams of water falling on your head? That's how lucky stylist Stepanida Kozlova is! Now her recently purchased apartment is uninhabitable, a new renovation is ahead, and, as we know, it’s worse than a fire... She had to move to the “Cozy Corner” boarding house, which in fact turned out to be not so cozy. One night Styopa found in her room... Batman flying through the window! And the neighbor, who treated herself to some candy in Kozlova’s room, ended up in the hospital with poisoning... To top off all the troubles, the blackmailer began calling Stepanida, threatening to make public the old story: she allegedly killed her classmate! Soon Styopa found out that a week ago a girl who looked terribly similar to her lived in the same room, but she disappeared without a trace... It seems that something creepy and incomprehensible is swirling around Stepanida, and it was not by chance that she ended up in this boarding house!
