Benjamin Zwyckoff’s brilliant invention – the oscillating sprinkler – is stolen from him by the Arthur Morgan Lawn and Garden Company. Zwyckoff challenges them in court. During the trial he gets trapped in his memories: the marble championship he won when he was a kid, the visit to Ebbets Field for Jackie Robinson’s first game, the great love of his life that he lost because she was black girl and he was a white boy, the struggles with his wife and son, and the inventions he never got to create.
