Part 7: While visiting Moscow for Kitty's confinement, Kostya quickly gets used to the city's fast-paced, expensive and frivolous society life. He accompanies Stiva to a gentleman's club, where the two meet Vronsky. Kostya and Stiva pay a visit to Anna, who is occupying her empty days by being a patroness to an orphaned English girl. Kostya is initially uneasy about the visit, but Anna easily puts him under her spell. When he admits to Kitty that he has visited Anna, she accuses him of falling in love with her. The couple are later reconciled, realizing that Moscow society life has had a negative, corrupting effect on Kostya.
