The Whales Of August(1987)
Summer people in Maine: things are changing. Whales no longer pass close to the shore as they did during the youth of two elderly widowed sisters who have a seaside home where they've summered for 50 years. Libby is blind, contrary, and seemingly getting ready to die. Sarah is attentive to her sister, worried about continuing to care for her, and half interested in an old Russian aristocrat who fishes from their shore. It's the eve of Sarah's 46th wedding anniversary. The Russian offers some fish he's caught, Sarah invites him to dinner, and Libby gets her back up. Sarah wonders if it isn't time to sell the place and find a home for Libby. What alternatives do old people have?
