Jeanne finds out that her almost ex-husband continues to live in her apartment with his mistress, and refuses to move out in a good way. Zhanna turns for help to a charming law teacher - Kirill. Who really likes Jeanne, and who really likes her sworn friend Vika. And Nastya discovers an unfamiliar world of erotic sites and new sensations. So new that you have to call an ambulance.

Zhanna and Nastya are going to sign up! Nastya - to follow their neighbor on the block Ulyana, and Zhanna - to remember her youth and not let Nastya prevent Ulyana from having fun. They are invited to the entrance by Danila, a fifth-year neighbor, who, to Nastya's great surprise, clearly sympathizes with her.
