Sam was experimenting growing string beans, but his crop turned out very poorly. Sam consults with his friend Ralph Barton, but Ralph has no answers. He then talks to Harry at the lawn and garden shop in town, but he's no help. Meanwhile, Millie is growing string beans in her backyard garden from Sam's seeds and they turned out big and beautiful. Goober drops off her car and sees the beans. Sam later sees Millie's beans and asks her what she did to get them to grow so well. Turns out Millie did nothing special but water them. Sam gets irritated when Millie sees a bucket of his tiny shriveled up beans. That night Sam and Millie are double dating with Goober and Marilyn. Sam becomes annoyed when Goober keeps complimenting Millie's beans. Afterwards, Millie tries to console Sam, but they wind up in an argument. Mike talks to Millie about her fight with Sam and her beans. Later, Mike tells Sam that Millie talks to her beans. Ralph sees Sam talking to his beans and tells Sam something that makes him feel better. Sam apologizes to Millie and brings her some of his tomato crop. After he leaves, she compares his tomatoes to hers and hers are bigger.
