`Supernanny' is back, and this time she's on a mission to help not only misbehaving kids but entire families that are in crisis. Calling `Family SOS' the next evolutionary step toward educating and helping families heal, Jo Frost shares her respected advice with families of all sizes and structures that are dealing with issues ranging from rebellious teenagers to bullying at school to battling parents on the edge of divorce. The hourlong episodes also incorporate topical situations, including families headed by same-sex parents and military families where a mom or dad has recently come home from overseas duty.
