Plot

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 and adjusting to her father's remarriage after her mother died some time ago. However, while working at her new job, she encounters Todd (Merwin Mondesir), a boy in her class, whom she has a crush on. However, Ashley (Maia Campbell), his older sister, dislikes her and criticizes her any way 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 (Phillip Jarrett), forbids 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.
