Kathryn Mewes visits the Smith family and attempts to ban smacking and restore order in a house where communication has broken down and chaos rules. The Smiths have turned to Kathryn in a desperate attempt to regain some control over their unruly children - Alessandro, Carmelina and Luciano. The kids rule the roost fighting and biting anyone who gets in their way, while ignoring their mum when she pleads with them to stop. After a full day of mischief they then spend every night bed-hopping, meaning no one in the house has slept properly in years. When Kathryn arrives at the family home on Stockton-on-Tees, she first has to deliver some tough home truths for parents Anthony and Angeline - it's them who have to change, not the children. Kathryn introduces a range of clever techniques. But when the kids fight back, dad is put to the test.
