Wilma receives a letter from her mother announcing her plans to move in with her favorite son-in-law and his wife. In response, Fred starts to renovate an old, run-down shack to accommodate Mrs. Slaghoople. However, Wilma soon discovers that her mother wasn’t talking about Fred but rather her other daughter's husband. Fred is initially thrilled about the news, but his excitement fades when he realizes the hefty amount he spent on the renovation.
