Sixteen-year-old Randy's behaviour deteriorates after his parents split up. He exploits the situation and does exactly as he pleases, knowing his father isn't around to enforce discipline. So it comes as a shock when his mother, Carrie, sick of her son's rudeness and disrespect, announces she is going to spank him. Randy endures a humiliating trip over his mom's knee and a bare bottom paddling which has him bawling like a baby. Unknown to Randy, his mother's friend Irene is responsible for suggesting that corporal punishment will help adjust Randy's attitude and behaviour. When Carrie gets a promotion at work and has to go away overnight on business trips, she asks Irene to move in and keep an eye on Randy. This doesn't go down at all well initially as Randy insists he is too old for a babysitter. However, his childish, petulant behaviour results in further spankings ... from Irene as well as his own mother.

As time passes, Randy guesses the nature of the relationship between his mother and Irene, and once it is confirmed, he accepts it, having become fond of Irene who has become his second mom. His spankings continue, nor do they end when he dates Roxanne, as she spanks him too! But by then, Randy is used to being disciplined by strong-minded, assertive women, and wouldn't have things any other way...
