A fascinating and vivid portrait of Camilo Castelo Branco, centered on one of the most remarkable episodes of his life, when the writer and Ana Plácido were imprisoned at the Cadeia da Relação do Porto as a result of the famous adultery trial that shook 19th-century Portuguese society. A collection of extraordinary stories about people marked by bitter lives — forgers, parricides, infanticides, and even a king — which Camilo heard there and later recounted, with his inexhaustible creative genius, in the book “Memórias do Cárcere”, adapted by the film.
