Olive, Again follows the blunt, contradictory yet deeply loveable Olive Kitteridge as she grows older, navigating the second half of her life as she comes to terms with the changes - sometimes welcome, sometimes not - in her own existence and in those around her.

Olive adjusts to her new life with her second husband, challenges her estranged son and his family to accept him, experiences loss and loneliness, witnesses the triumphs and heartbreaks of her friends and neighbours in the small coastal town of Crosby, Maine - and, finally, opens herself to new lessons about life.
