Amy Hart, an orphan scholarship student, is bullied at school by the heiress Belle Sterling. Weeping before an ancient mirror, she sees a face exactly like hers—Vera Beaumont, a duke's daughter in the Middle Ages who is being forced into marriage by her mother. The two switch places through the mirror. Vera takes Amy's place at school, dumping a milkshake over Belle's head and making everyone meet "Amy" anew. Amy takes Vera's place in the castle, meeting nobleman Arthur at a garden tea party and a boat ride on the lake; he falls for her—for who she truly is, not her title—and crowns her with the family tiara and a proposal ring. The Sterlings lose their standing and Belle transfers away; the duke drops the marriage arrangement and lets Vera study. Mirror and mirrored world each find their home, and two families become one across the glass.
