The central conflict ignites when Anna Karenina, a high-society woman, abandons her marriage for an illicit affair, setting her on a collision course with the rigid moral expectations of 19th-century Russian aristocracy. Anna seeks personal fulfillment and emotional authenticity, but she faces intense social ostracization and the internal erosion of her own identity. She is opposed by the cold, bureaucratic rigidity of her husband, Karenin, and the unforgiving judgment of the social circles she once inhabited. The narrative framework utilizes a multi-perspective approach, alternating between Anna's descent and the parallel, more grounded development of Levin, whose search for meaning provides a logical counterpoint to Anna's tragic trajectory.

Readers and critics frequently highlight the novel's ability to balance intimate character studies with broad social critique. Discussion often centers on the stark contrast between Anna's destructive passion and Levin's search for spiritual and practical purpose. Many observers note that the pacing is deliberate, allowing for deep immersion into the internal lives of the characters. The work is widely recognized for its psychological depth and its refusal to offer simple moral solutions to complex human dilemmas. Critics often emphasize that the text remains relevant due to its honest portrayal of the tension between individual desire and societal constraints.
