Dmitri Gurov is a Moscow bank worker, married with a daughter and two sons. Unhappy in his marriage, he is frequently unfaithful and considers women to be of "a lower race". While vacationing in Yalta, he sees a young lady walking along the seafront with her small dog, and endeavors to make her acquaintance. The lady, Anna Sergeyevna, is also vacationing, while her husband remains at home in an unnamed provincial town. They are soon engaged in an affair, and spend most of their time together walking and taking drives to nearby Oreanda. Though she is expecting her husband to come to Yalta, he eventually sends for her to come home, saying that something is wrong with his eyes. Gurov sees her off at the station.
