In the sweltering summer of 1938, with Lisbon in the grip of Portugal's dictatorship of António Salazar, a journalist is coming to terms with the rise of fascism around him and its insidious impact on his work. Consumed by the passing of his wife and the child he never had, Pereira lives a quiet and lonely existence. One day, the young and charismatic Monteiro Rossi enters his life, changing everything. A man who once shied away from criticizing Portugal's authoritarian regime finds himself unable to stay quiet any longer, resulting in his political awakening and a devastating act of rebellion.
