When her twenty-two-year-old stepdaughter announces her engagement to her pandemic boyfriend, Sarah Danhauser is shocked. But headstrong Ruby has already set a date (just three months away!) and spoken to her beloved safta, Sarah’s mother Veronica, about having the wedding at the family’s beach house in Cape Cod. Sarah might be worried, but Veronica is thrilled to be bringing the family together one last time before putting the big house on the market.

But the road to a wedding day usually comes with a few bumps. Ruby has always known exactly what she wants, but as the wedding date approaches, she finds herself grappling with the wounds left by the mother who walked out when she was a baby. Veronica ends up facing unexpected news and must revisit the choices she made long ago. Sarah’s twin brother, Sam, is recovering from a terrible loss, and confronting big questions about who he is—questions he hopes to resolve during his stay on the Cape. Sarah’s husband, Eli, who’s been inexplicably distant during the pandemic, confronts the consequences of a long ago lapse from his typical good-guy behavior. And Sarah, frustrated by her husband, concerned about her stepdaughter, and worn out by the challenges of the quarantine, faces the alluring reappearance of someone from her past and a life that could have been.
