Alison Bagnall’s The Dish and the Spoon opens with Rose (Greta Gerwig) despondently crying as she drives to the beach—clad in pajama bottoms, a boxy coat, and knit cap—after discovering her husband’s infidelity. Taking refuge from the winter air in a WWII watchtower, she discovers a young British drifter (Olly Alexander) shivering inside.
