A year after the death of her husband, Henry, Emily Maxwell gathers her family by Lake Chautauqua in western New York for what will be a last holiday at their summer cottage. Joining is her sister-in-law, who silently mourns the sale of the lake house, and a long-lost love. Emily's firebrand daughter, a recovering alcoholic recently separated from her husband, brings her children from Detroit. Emily's son, who has quit his job and mortgaged his future to pursue his art, comes accompanied by his children and his wife, who is secretly heartened to be visiting the house for the last time.
