Highly successful first part of the "Schulmädchen-Report" series: When Renate is caught having sex with the bus driver on a school trip, her school promptly reacts with a faculty meeting. At first, Renate is to be expelled from school immediately, but then sexual psychologist Dr. Bernauer persuades her teachers to give her a second chance. At the faculty meeting, Bernauer then describes similar cases that become episodes in the frame story of the sex film.
