A child, Melissa, waits patiently in a room. A social worker, May Foster, lets her in and asks Melissa to share why she has been suspended for the third time. The child answers that she got in an argument with her history teacher.
May asks about her home life, which Melissa answers honestly. The child then tells May that her father was a wizard and that she is 2400 years old. May invites Melissa to meet her husband, a fantasy-lover.
Melissa sits at the dinner table with May, her husband, and her father-in-law. After some small talk, Melissa shares that her father, the magician, was working on a potion to restore youth. He found a way to stop aging in the children, but the knowledge is useless to adults. She is looking for a new foster home and wants May’s family to take her in. They accept.
Later, she discusses the results of scientific research with her grandpa (May’s father-in-law), who is a biochemist, as they try to turn Melissa’s potion into an age-reversing potion. They are unsuccessful. He asks her if she wants to grow up at some point, to which she says no because she does not want to die.
Five years later, Melissa is in a church, reflecting on her time with the Fosters, which is now over. After her “grandpa” had a stroke, George became resentful of Melissa and her inability to help his father. He started following Melissa when she was going into the woods to make her potion, and stealing samples, made in such a way that they could not be studied. She decides it is time to leave and just in time: they had called the authorities. She is very tactful in her escape, sowing misinformation that she is headed to Berkeley before settling in to a triple feature for children at the movie theater.
