Horatio King is an eighty-five-year old curmudgeon who happens to be the greatest musical theater composer and lyricist of his generation. Fifteen years before the story begins, his last musical, “Black Hawk Down,” was a flop. Now King is approached by twenty-five-year old Ben Willis who sends him a copy of his newly published children’s novel, “The Worldwide Dessert Contest.” Would King like to get back in the game and collaborate with a new-comer on what could be his last Broadway musical?
