Seven months after the third movie, everyone goes to Hawaii. Yes, Susan Wyatt and Sharon Grand (Hayley Mills), the Wyatt twins — Lisa, Jesse ad Megan (Leanna, Monica and Joy Creel) — and their dad Jeffrey (Barry Bostwick). Jeffrey has inherited a resort just in time for his honeymoon with Susan. Sharon plans on taking care of the girls, but seeing as how this was a two-parter, there has to be some drama.
Mollie Miller directs (she also did the third movie) and this was written by John McNamara, who created the series Aquarius and The Magicians.
This movie has my favorite thing ever happen: both Susan and Sharon have exactly one photo of themselves together from their childhood and, of course, it’s the publicity photo of them in the tent from the first film. No one was there with a camera. It would be impossible to have this image. And here it is, captured, a memory of their past which is our past which we remember directly than them.
