Die sündige Kleinstadt (1975)

Three pretty schoolgirls of marriageable age giggle and cackle while lying naked in bed as they read from the erotic notes of one of them, which are compiled in a notebook called "My intimate diary". One day, the author of these late-pubescent outpourings, Monika Hannemann, daughter of a town councillor, leaves her erotic fantasies in the classroom, whereupon these lines fall into the hands of the slippery teacher Miss Stubentreu. She reads them and learns from the lines that Monika must have become a village mattress and slept with half the men in Bumburg. Soon the erotic content is making the rounds, becoming the talk of the small town, and the conjectures and insinuations about who had or could have had what with whom in Bumburg run rampant. Even a reporter named Waltraut Henze, who has few scruples, arrives because she senses a sensational story behind the scribblings.
