The Prussian principal runs the school with an iron hand, believing that discipline and hunger strengthen a girl's character.

Manuela's mistake is to announce her love in front of guests and students at a party following a school play. How will the principal discipline Manuela, and how will Fraulein Von Bernberg, Manuela, and the other girls react to the principal's decisions? Written by

Siamo in Germania, negli anni '30. A Potsdam, in un collegio femminile, vige un'educazione rigida e severa. Manuela, una allieva molto introversa, è conquistata da una insegnante molto comprensiva, che usa metodi molto diversi da quelli imposti dall'Istituto, e piano piano si lascia trascinare verso un affetto morboso per la donna. La giovane inizia a sognare carezze e gesti di affetto dell'insegnante. Dopo qualche tempo c'è la recita scolastica annuale e, nell'euforia, Manuela si ubriaca e confessa pubblicamente il suo amore per la docente. Scoppia lo scandalo e la direttrice ristabilisce l'ordine con severi provvedimenti disciplinari. Presa dallo sconforto e piena di sensi di colpa, la studentessa decide di suicidarsi, ma viene salvata dalle compagne di scuola. Written by rosebud6
