A crisis develops in the Oblonsky household when Dolly finds out about her husband's affair. Stiva's sister, Anna Karenina, arrives to reconcile the couple and dissuades Dolly from getting a divorce. Konstantin Levin, Stiva's friend, arrives in Moscow to propose to the eighteen year old Kitty Shtcherbatsky. She refuses him, for she loves Count Vronsky, a dashing army officer who has no intentions of marrying.
Meeting the lovely Madame Karenina, Vronsky falls in love and begins to pursue her. He and Anna are so involved with each other at the grand ball that Kitty's hopes for Vronsky are shattered. Anna, followed by Vronsky, returns to her husband and son in St. Petersburg, while the disappointed Levin returns to his country estate.
