Boldly following Anna back to St Petersburg, Vronsky makes it known to society that he is the companion of Anna – a notion she does nothing to stop. Soon, society is whispering about the affair, and it's only a matter of time before Karenin learns of the relationship. Outwardly more worried about his social and political position than his wife's passion, he orders her to break off with Vronsky or risk losing her son. She tries, but cannot tear herself away from Vronsky.
