Every summer four old friends flock together at Madge's seaside house to swap stories and sip wine. Throughout divorces, children, and new marriages, only the beach house and the sisterhood that comes with it, hold constant. This time, though, something is different
Madge, the writer friend who brought them all together, is acting strange. She asks them for a risky, unthinkable favor. And then one morning, she disappears.
In Madge's absence, her friends discover the unfinished manuscript to what will be her final novel. It is the story of past forty years of their lives, a story that may reshape their futures.
