In 1972, Maria Isabel Barreno, Maria Teresa Horta and Maria Velho da Costa published the book As Novas Cartas Portuguesas [New Portuguese Letters], addressing topics forbidden and censored during the Estado Novo regime such as the colonial war, adultery, rape and abortion. The book was immediately banned and the writers were prosecuted for crimes against morality. The legal proceedings caused waves of protest around the world, giving rise to an international network of solidarity. In the film, the “three Marias” tell their story, before and after one the first major feminist struggles in Portugal.
