The three Bernstein-Flynn sisters are reunited when Nora returns to Los Angeles after two years in Africa and Annie graduates from college. Big sister Bess, who is expecting her first child any moment, is thrilled to have her two sisters back in the nest, but husband Steven is less enthusiastic as he realizes that when he married Bess, he got more than he bargained for. Instead of getting one woman, he ended up with three: his wife and her two sisters. Meanwhile, Nora makes a discomfiting discovery of her own when she learns the truth about her ex-husband's sexual preferences.
