Following her daughter Emily's divorce, Sarah allows both Emily and her granddaughter, Katie, to come and live with her. Sarah cynically recalls how Emily used to behave when she lived at home before she got married, and she soon realises that nothing has changed. In fact, Katie is almost as bad as her mother, judging by the state of her untidy bedroom and coming home late. With a huge workload of additional household chores and Emily's bedroom resembling a pigsty, Sarah decides to take action... it's time for some well-deserved bare bottom spankings. House rules are outlined, and Grandma gives her daughter and granddaughter a stern talking to, explaining the consequences when house rules are broken. She refuses to tolerate Emily's rudeness and temper tantrums, and spanks her 38-year-old daughter like a naughty little girl. Katie doesn't escape discipline either. It seems that Grandma knows exactly how to take charge and keep her unruly family in line, with the help of her heavy-duty spanking arm and a paddle hairbrush!
