The movie has been included as a bonus feature on the Sister, Sister complete collection box set released March 2016. The film stars Tia & Tamera, and their brother Tahj Mowry. The film was directed by Jeffrey W. Byrd.

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 bans him from making more experiments in his lab until he learns responsibility in them. 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.

When his grandmother Cat (Hope Clarke) mistakenly uses the tainted soap, she's transformed into a 17-year-old (Tamera Mowry). Her ex-husband Gene (Robert Hooks) follows suit, and is also returned to his teenaged self (Mark Taylor).

Cat and Gene are having a fine time reliving their youth and enjoying the thrill of teenage romance, but there's a fly 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. In Sydney's room, she and Cat finally have a long and heartfelt talk. Sydney admits she's homesick for California and her old friends. She hates Connecticut and the bullying she is subjected to by Ashley and her friends because Ashley's brother is interested in her. During that time, Cat admits her earlier experience with Ashley. However unlike Sydney, she was able to stand up to her and earn Ashley's begrudging respect.
