When your husband of twenty years divorces you for a woman half his age, it's time to move on to Plan B. For Reba Hart (Reba McEntire), that means not only accepting that her marriage is over, but also accepting that her ex's new wife is pregnant. If that isn't disruptive enough, Reba learns that her 17-year-old daughter is pregnant too. So it's out with the old and in with the new as hubby leaves and son-in-law arrives. With al the outrageous domestic obstacles thrown in her path, Reba realizes one thing for sure: life will never be the same in this dysfunctional household!
