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.

When Steven puts his foot down and insists that only he and Bess will be present in the delivery room during the birth of their baby, the Bernstein-Flynn family, crushed by Steven's edict, plays a waiting game of their own.

When Annie's latest income-generating schemes prove to be predictable disasters, Bess and Nora decide it's time for a sisterly intervention. But Steven has a simpler solution -- and offers Annie a job working for him and Jake. Everything seems to be going so well, Bess and Nora begin to question their female perspective on the situation -- until fate intervenes. Meanwhile, George blindsides Nora with some unsolicited fatherly advice.

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.

When Steven's well-appointed and domineering mother and counterculture dropout father arrive together from Chicago to visit their son and daughter-in-law, Steven's coping strategy is to stay under the radar until the visit is over, but Bess encourages him to renew his bonds with his parents and invites them to extend their visit. It isn't long, however, before Steven's mother's controlling nature tries even Honey's patience. Meanwhile, his father's inappropriate behavior annoys George and grosses out Nora and Annie.
