Lonely and insecure, 38-year-old Lyubov, a kindergarten teacher, comes home and discovers a thief in her apartment. Having called the police, she remains to wait for them and, having a large heavy body, props up the front door from the outside so that the thief cannot escape. Realizing that he is locked, the thief Sergei tries to get out of the apartment: first he intimidates, and then turns on all his charm, realizing that she is not only lonely, but also passionately desires love.
