It's 1990. In Dalton, Maine, life goes on. Rose goes to work at the diner every day, her bruises hidden from both the customers and her two young boys. At a table she waits, Dr. Richard Haskell looks back on the one choice that's charted his entire life, before his thoughts wander back to his wife, Trudy, and her best friend. Trudy and Bev have been friends for longer than they can count, and something more than lovers to each other for some time now—a fact both accepted and ignored by their husbands.

Justine is 21 years old, and has lived with her grandparents and her cousin Jules since the death of her parents. As a nursing assistant at a retirement home, she spends much of her days listening to her residents’ stories. After bonding with Hélène, an almost 100-year-old resident, the two women slowly reveal their stories to one another. Whilst Justine helps Hélène to relive her memories of love and war, Hélène encourages Justine to confront the secrets of her own past and the loss she keeps buried deep within.

In 1938, a dead whale washes up on the shores of remote Welsh island. For Manod, who has spent her whole life on the island, it feels like both a portent of doom and a symbol of what may lie beyond the island's shores. A young woman living with her father and her sister (to whom she has reluctantly but devotedly become a mother following the death of their own mother years prior), Manod can't shake her welling desire to explore life beyond the beautiful yet blisteringly harsh islands that her hardscrabble family has called home for generations.

After years away from her family's homeland, and healing from an affair with an established director, stage actress Sonia Nasir returns to Palestine to visit her older sister Haneen. Though the siblings grew up spending summers at their family home in Haifa, Sonia hasn't been back since the second intifada and the deaths of her grandparents. While Haneen stayed and made a life commuting to Tel Aviv to teach at the university, Sonia remained in London to focus on her burgeoning acting career and now dissolute marriage.

For fifty years, Abe and Jane have been coming to Central Park, as starry-eyed young lovers, as frustrated and exhausted parents, as artists watching their careers take flight. They came alone when they needed to get away from each other, and together when they had something important to discuss. The Park has been their witness for half a century of love. Until now. Jane is dying, and Abe is recounting their life together as a way of keeping them going: the parts they knew.
