With five rambunctious boys in a small house, Ken and Vania have reached the end of their rope -- and possibly the end of their marriage. Vania has filed divorce papers and Jo Frost is the family's last hope for reconciliation -- if this doesn't work, Vania will move forward with the divorce. Ken is a strict disciplinarian, while Vania prefers a more laid-back method of child rearing. Rather than compromising, they've gotten to the point where they simply avoid dealing with the kids at the same time -- if one parent is there, the other is out -- and the kids have learned to use them against each other as they act up, fighting with each other and for their parents' attention. Matters are further complicated by Ken's relationship with the older boys; the little ones, Brendon (4) and Christian (3), are his and Vania's together, while Myca (5), Dawson (8) and Alex (9) are from Vania's previous relationships. Ken's biggest issue is with Alex, the oldest son, with whom he often clashes. The difference in parenting styles and the problems between Alex and Ken have brought this marriage to the breaking point -- can Supernanny get this couple back on track?
