The main character of the play is called Alexey. He finds himself an unwitting witness to the death of a young girl who fell out of a window. Alexey, who did not have time and was not able to at least somehow help her, feels guilty for what happened. He almost feels like a killer. And this feeling pushes him towards social activity. He collects things for a charity event, visits a nursing home, takes a boy from an orphanage to the planetarium... Everywhere he tries to find a way to cleanse himself of his feelings of guilt. And this is very difficult, because he seems to have lost his bearings and no longer quite understands what is truly good.
