An orphan is sent to a reformatory where the inmates receive an extremely repressive education. While visiting the place, a teacher hears the orphan's indignant complaints about the mistreatment. Impressed, he adopts this 16-year-old girl, who at 24 graduated in Social Sciences. Now she has a name: Vitória dos Santos, and her concern is to help the girls who, like her, suffer in the city's asylums.
An ordinary thief and two accomplices invade a mansion whose owners traveled to Buenos Aires. They settle there with the whole family, until the real owners return. The owner's natural son saves the thief's situation when he threatens to reveal some compromising documents.
