Manuela von Meinhardis, whose mother had died when she was young and whose father serves in the military, is enrolled at an all-girls boarding school headed by the traditional and iron-fisted Fräulein von Nordeck zur Nidden. Manuela is immediately exposed to the strictness of the school when receiving her uniform and having many of her possessions taken from her. While the other girls at the school receive Manuela with open arms, she still feels very out of place, until she meets Fräulein von Bernburg, a teacher at the school. After witnessing Fräulein von Bernburg's compassion for the other girls, Manuela develops a passionate love for her teacher. The first spark of love begins with a goodnight kiss. While the teacher normally gives all the girls a goodnight kiss on the forehead, Manuela receives one on the lips.
