When Annabelle makes her first visit to Mom and Arnie's new apartment, she's struck by how different Arnie seems. Thrown off by the bustling city and feeling left out, Annabelle begins to feel like she's on the outside looking in.
Arnie and Annabelle are shocked and angry to learn that both their parents are interested in dating other people. Could the siblings' deepest wish--for their family to reunite--still come true?
When Arnie and Annabelle Beeler find out their parents are separating, they make one last attempt to keep their parents together by creating a video montage of their favorite family memories.
This is the first holiday the Beelers will celebrate separately. At the end of the weekend, Annabelle and Arnie are surprised when Dad makes an unexpected announcement.
