Nude sunbathing and spanking with a submissive girlfriend lead hedonistic Sandra Shanks to the rigors of Quirke's School, where adult schoolgirls are taught old-fashioned submission, in the stern modesty of too-tight uniforms. Strict discipline means 'baring up below' for bare-bottom caning or birching, with refinements like the hoop and cage, and the noble art of nude female boxing. In a school without males, the dormitory fun of 'all girls together' is as deliciously naughty as Sandra imagined - until she learns sadistic Miss Quirke's own guilty secret.
