Seventeen Again

When the Donovan family moves from California to Connecticut, 17-year-old Sydney (Tia Mowry) finds it is not easy being in a new town away from her old friends. However, she soon develops a crush on a classmate while trying to compete with his older sister, Ashley (Maia Campbell), who dislikes her and criticizes her anyway she can. Her 12-year-old genius brother Willie (Tahj Mowry) is happy as long as he can tinker in his lab with his increasingly complex experiments. When another experiment goes wrong, their father, Barry, bans him from making more experiments in his lab until he learns responsibility. Willie is convinced he can defeat the aging process, and while devising an experimental anti-aging formula, he accidentally spills some on a bar of soap.
