This San Antonio family is bursting at the seams with kids, conflict and aggression. Stay-at-home mom Joey-Lynn and her husband, Glenn, have five spirited daughters and a granddaughter all living under the same roof, and the exhausted couple have abdicated discipline. Their oldest, Samantha, 20, had a child as a teenager - their granddaughter Krissy, now age 2. Joey-Lynn and Glenn had Samantha when they were teenagers themselves, and feel as if they have failed as parents since Samantha had a promising future that has been changed by her young motherhood. Samantha and her next-oldest sister, Brooke, 17, despise each other and curse at each other in front of the younger siblings -- Savannah, 10, Hailey, 6, and Haidyn, 1+1/2 -- who in turn act out with boundary-pushing and aggressive behavior. Mom defers all discipline to Dad, who simply yells and doesn't follow through. Can Jo help this family defuse the anger?
