Having been suspended from school, Ali's father arranges for Mr Pullman, a disciplinarian at Brookhaven Academy of Behaviour, to visit their house. He is extremely strict and spanks Ali for anything that displeases him. She is subject to further humiliation and embarrassment when Dr Murphy, also from the Academy, arrives to examine her. Later, Ali is left alone in her room while her father and younger sister go out for dinner. On returning home later that evening, Ali's mother confronts her husband about it and, following an argument, she, too, ends up getting a spanking.

Things worsen even further for Ali when she is sent to spend ten days at Brookhaven Academy while the rest of her family go on a cruise. Things are hard for her at the Academy where she finds herself on the receiving end of numerous spankings and further humiliating 'medical examinations'. When the ten days are finally over, Ali waits for her father to arrive. One question remains, however, will he take Ali home with him, or leave her at the mercy of Mr Pullman?

This is the third and concluding part of the Ali in Trouble series.
