"The Beales of Grey Gardens" gives greater insight into the simultaneously contentious and loving relationship between the mother and daughter, as well as their relationship with the young caretaker, Jerry, their multitude of cats, and Lois Wright, a friend who briefly appeared in "Grey Gardens" at the celebration of "Big" Edie's birthday.It includes a dramatic scene of a small fire in the second floor hallway of the mansion, which explains the large hole in the wall shown in the first film.
