Alexander Brennan is a confirmed delinquent. When his single mother goes abroad to work he is sent to his Aunt, a headmistress in a Portland private school. She enrolls him in the local co-ed, but his behavior worsens and when he becomes involved in arson at the school he has to hide. His Aunt begins to dress him as Alexandra and the delinquent begins the process of becoming the pretty and delightful Alexandra. The terror and humiliation are almost too much to bear when she enrolls him in her own private school, a girl's school. But slowly the new schoolgirl adjusts to her new circumstances and she discovers there are many compensations to being a pretty and popular girl. There are problems too, corsets to control her figure, always too tight and uncomfortable. The school uniform is humiliating, short skirt, white blouse, blazer and raincoat. When a school trip to San Francisco brings matters to a head Alexandra has to make decisions about the future. Her beautiful best friend Emily, a lesbian, is keen to make sure that the new schoolgirl makes the right choices.
