For nearly four decades, lifelong friends Jude, Wendy, Adele, and Sylvie have seen each other through romances, child-rearing, changing careers, divorces, medical recoveries, and general aging. But now Sylvie has died, and the three remaining women are tasked with cleaning out her beach house before it's sold. Thrust together in this weathered old house on the ocean, where the ghosts of their younger selves compete with their current realities, the women ponder a collective lifetime of loves and grievances, disappointments and successes, and ultimately, how a life can change in a single unexpected instant - or over the course of a weekend.
