Summer of 1870. Two writers, Eça de Queiroz and Ramalho Ortigão, decide to write a four-handed whodunit for the daily "Diário de Notícias". Could it be that the story they wrote as fiction is based on a real case? This question fuels the conflict between the two writers and drives them to a nearly fatal duel. Lisbon is in commotion. One crime follows another in a story in which love is stronger than tradition. Everything happens at frenzied pace, as in a game.
