In 1874 Russian Empire, Prince Stephan "Stiva" Oblonsky's wife, Princess Darya "Dolly," banishes her husband from their home due to his infidelity. Stiva's sister, Anna Karenina, a well-off and well-liked socialite living in St. Petersburg with her older husband, Count Alexei Karenin, and their son, Sergei "Seryozha" Alexeyich Karenin, travels to Moscow to persuade Dolly to forgive Stiva. Stiva meets his old friend Konstantin Levin, a wealthy land owner and aristocrat who is looked down upon by Moscow's elite for preferring country life to city life. Levin professes his love for Stiva's sister-in-law, Princess Ekaterina "Kitty" Alexandrovna, and Stiva encourages him to propose. However, Kitty declines as she hopes to marry Count Alexei Vronsky, a wealthy cavalry officer. Levin meets with his elder brother, Nikolai, who has given up his inheritance and taken a prostitute named Masha as his wife. Nikolai suggests that Levin marry one of the peasants on his estate. On the train to Moscow, Anna meets Vronsky's mother, Countess Vronskaya, facing scandal for her own infidelity. Once there, Anna meets Vronsky himself and they have mutual attraction. After a railway worker is killed in an accident at the station, Anna asks if anything can be done for his family. Vronsky is seen giving a large sum of money to other railroad workers for the deceased's family. Anna convinces Dolly to take Stiva back. At a ball that night, Kitty attempts to dance with Vronsky, but he dances with Anna, leaving Kitty heartbroken. Vronsky later tells Anna that he must be wherever she goes.
