After stirring society by leaving her groom at the alter and going directly to a prostitution house, a young model becomes the city's most famous harlot, known as “Hilda the Hurricane“, in the 50's Brazil. She could do fine if it wasn't for Malthus, a young novice said to be a saint, for whom she falls in love. However, the boy is kept under the strict, severe doctrine of Father Nelson, a conservative priest intolerant even to every minor sin. Things start getting harder when Roberto, Malthus' old friend and a communist reporter (the actual author of the story), tries to interview Hilda and disclosure the real reasons behind her radical change of mind. In the meantime, the middle-classes are terrified by the “leftist threat“ in Brazilian politics.
