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.

Nora realizes it has been nearly four years since she went out on a date. Little sister Annie offers to help her get back in the game, but the two couldn't be more different in their approach when they visit a singles bar. Meanwhile, Bess has trouble telling if the pangs she's feeling are labor pains or twinges of jealousy at being left out while her single sisters cruise for men.
