Annie's half-sister Lilly (guest-star Michelle Phillips, "Knots Landing" and musical group "The Mamas and The Papas") is getting married and wants their ailing father to walk her down the isle but Annie worries that the strain might be too much for him. Meanwhile, Fred (guest-star Al Ruscio) and Mrs. Bink (guest star Eileen Brennan) attend premarital counseling with Chandler, but Fred's mother (guest-star Carol Arthur) tries to put a stop to the wedding because she thinks Mrs. Bink is a gold digger. Lastly, Jimmy (guest-star Glen Poehlman) and Pat (guest-star Pam Rawuka), two mentally challenged people, decide to get married after just one date and ask Chandler to perform the ceremony, but Jimmy's parents (guest-stars Dick Van Patten and Patricia Van Patten) try to put a stop to it.
Reverend Eric Camden and his wife Annie have always had their hands full caring for seven children, not to mention the friends, sweethearts and spouses that continually come and go in the Camden household. This year, Eric and Annie will find their family back together in Glenoak with the return of Matt and Simon.
As is often the case when the house is overflowing with Camdens, Eric and Annie are in for a bumpy ride as their children take landmark steps in their lives. Meanwhile, Eric and Annie continue their journey as soul mates, parents and grandparents whose love and respect for each other brings them ever closer.
Through all the ups and downs, Eric and Annie have managed to keep their romance alive and their family together. Not only are they raising their own seven children, they've picked up several additional family members along the way.
