Robert Fenton and his mother are taken in by the austere Miss Pauline Bunn. A life of drudgery stretches ahead for both of them and, as a Very Naughty Boy, Robert soon makes the acquaintance of “Arabella”, the cane which Miss Bunn hangs behind his bedroom door. The fanatically religious Miss Bunn allows Robert out only to go to school, where beatings are frequent, and to Bible Class at the local Church. He is accompanied by attractive Jane Gilmore, who is believed by Miss Bunn to be a good moral influence on the boy. However, Jane proves to be a minx who teases Robert and leads him on. Jane and her friend Amy Keeler enjoy getting Robert into trouble. Things are not as they seem when their Bible Class teacher finds them in the girls’ toilet together. But Robert is blamed and punished publicly. Jane’s parents are horrified when they catch their daughter and Robert in a state of undress. The errant pair are spanked soundly on their bare buttocks and forbidden to see each other again. After Robert falls ill, he is sent to a Convalescent Home by the local authority. But a mistake is made about his age and he finds himself in a ward where the discipline imposed by the nurses and the toilet regime are more appropriate for younger children. He attempts to escape, but is brought back by the police and chastised in front of the other patients and the Board of Guardians. Eventually Robert succeeds in getting away from Miss Bunn’s tyranny. He becomes a servant to a fading film star and then lands a role in a TV soap opera. But he is still treated like a Very Naughty Boy!
