Sarah is an unpopular girl with presumably low self esteem, as she doesn't like her appearance. She is obsessed with the idea of being "beautiful" and wants to be popular.
One day, on her way home from school, she comes across Eleanor in a scrapyard. Finding her absolutely gorgerous, Sarah takes Eleanor home and cleans her up. When Eleanor awakens, she shows gratitude for what Sarah had done and says that to show her appreciation, she would grant any of Sarah's wishes. Sarah wishes to be beautiful, and Eleanor agrees to grant this wish. She gives a heart-shaped necklace to Sarah, telling her to never take it off under any circumstance, to which Sarah agrees.
From then on, every night, Eleanor would sing Sarah to sleep before changing an aspect of her body to make her appear more beautiful. Sarah is very thankful for this, as it gets her much more attention at school, especially from her crush and the popular girls.
One day, at school, Sarah falls over, the necklace coming off her neck. Slowly, her body begins turning into scrap metal and junk. As her body continues to slowly turn, Sarah runs home. In her house, she finds garbage bags full of her own body parts.
Still steadily turning into a pile of junk, she sees Eleanor, now sporting a heart-shaped necklace of her own. Pressing a button on the necklace, Eleanor takes the appearance of Sarah, particularly the one she had before Eleanor began to make her "beautiful". She then walks away, leaving Sarah to die alone.
