[1] 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.

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.

Willie is convinced he can defeat the aging process, and while devising an experimental anti-aging formula, he accidentally spills some on a box of soap.

When their grandmother Cat (Hope Clarke) unknowingly uses the tainted soap, she is transformed into a 17-year-old (Tamera Mowry).

Cat and Gene are having a fine time reliving their youth and enjoying the thrill of teenage romance, but there's an error in the ointment.

Willie learns his formula could have deadly side effects, and now he must discover an antidote to return his grandparents to their older but healthy bodies.

Cat says yes, but then the happiness is interrupted by Sydney and Willie's dad, Barry and step-mother, Monique (Tonya Lee Williams) coming home from a trip.

The film went on to find greater popularity throughout the early-mid 2000s from frequent airings on Disney Channel.
