A wealthy businessman, Igor is bored in the company of his girlfriend Ilona – a glamorous secular lioness who, more than himself, loves his money and wants to become a pajamas designer at his expense. Meanwhile, a pulmonologist, Andrew, returns to Khrushchev. His wife, an employee of the passport desk Irina in a robe and curler, requires sex, for which he has neither the strength nor the desire. 10 years of routine in marriage have killed any passion for this couple. In order to satisfy her sexual needs, Irina masturbates in the photo of the famous Ukrainian singer Oleg Vinnik.

Igor and Irina encourage their partners to engage in a sexual experiment – a swinging evening. What if these pairs are exchanged by partners?

Meanwhile, a 30-year-old English teacher of the world was exposed by a lover naked on the balcony when his wife suddenly returned to the apartment. Only her neighbor on the balcony Denis can save and heat her. But the evening ceases to be sluggish when on the doorstep of Denis appears producer Edward.
