Vera and Kostya Nikitin have been married for seven years. Lately, Vera has noticed her husband's cooling towards her. She suspects that Kostya has a mistress, a young colleague Katya Lavrova. Kostya is going on his next business trip with her. One evening, fleeing the rain, Vera enters a small cafe and meets the waiter Anton. The young man studies at the university and, in order to pay for his studies, works part-time as a waiter in a cafe. A chance acquaintance develops into a strong passion, and Vera and Anton practically do not part for ten days. But the time comes and Konstantin returns from a business trip.
