Dorothy, Rose, and Blanche are three women who share a house in Miami, Florida. Dorothy's elderly mother, Sophia, unexpectedly moves in after her retirement home burns down, and Blanche accepts a proposal of marriage.
Blanche's sister, Virginia, with whom she has had a tense relationship for years, comes to visit. She reveals that she needs a kidney transplant to save her life.
Blanche dates an aerobics instructor who is considerably younger than she is. Meanwhile, Rose's mother comes to visit and resents the way her daughter treats her.
Blanche's father visits, telling that he has sold the family mansion to finance his dream to become a country music singer. Dorothy disputes with the girls' next-door neighbor over storm damage.
The girls remember how they came to live together; Blanche put an ad for a room for rent on a grocery store bulletin board, and Rose and Dorothy answered it.
