Rachel has now fully recovered from her stroke, and her outlook on life has taken a whole new direction where she is more carefree and is enjoying the small pleasures that life has to offer her. Meanwhile, the townsfolk are preparing for the 1911 version of the annual Avonlea Fair. Simon, the fair chairperson, has taken it upon himself to hire a midway, much to the chagrin of some of the more traditional members of the organizing committee, such as Hetty. But based on stories that Rachel has told him, Davey is enthralled by the midway attractions, specifically the live mermaid named Melusina, again much to the chagrin of Hetty, who has forbid him or Dora to go to the midway. But the more enthralled Davey becomes with Melusina, the more he learns about her and the midway owner, Mr. Snibb, and the main purpose of their business. In the end, Davey and Hetty learn that Rachel's new outlook on life has something to teach them.
