Four older women have a lifelong friendship of the best kind: loving, practical, frank and steadfast. But when Sylvie dies, the ground shifts dangerously for the remaining three. Struggling to recall exactly why they've remained close all these years, the grieving women gather at Sylvie's old beach house to clean it out before it is sold. Can they survive together without her? Without Sylvie to maintain the group's delicate equilibrium, frustrations build and painful memories press in. Fraying tempers, an elderly dog, unwelcome guests and too much wine collide in a storm that brings long-buried hurts to the surface --- and threatens to sweep away their friendship for good.
