Phineas and Bruce, both 75, have been neighbors in Florida for ten years. Phineas never married and Bruce is a widower. They are at opposite ends of the political spectrum, but still enjoy sharing drinks and watching the sunset most nights, which they call their sunset cocktail hour. Phineas is very conservative with some rather unusual political ideas. He likes to write letters to the editor which rarely get published. When one of them does get published, it goes viral and radically changes both of their lives. Phineas becomes the new darling of the conservative wing of the Republican Party. After his unfortunate death, Bruce investigates Phineas’ past to try to understand why he never found love and ended up so politically extreme.
