The Ghostly Apartment

Nikita, after having a quarrel with his mother, leaves his little sister at home alone and goes out to hang out with friends, and upon returning, finds himself in a strange place.

Now, in his apartment, live the aristocrat Elizabeth Razumovskaya from the 1920s, a girl Lidotchka from the 1970s, and a Ghost from the future.

To return, the hero needs to realize his mistakes and make a difficult choice: accept being trapped in the ghostly apartment or help others escape from it.
