Awakened one morning by police officers and taken without further explanation to a clandestine and illegal prison, José Zurin, a young business administrator, is involved in the political game of repression. All because, the day before, he had met Pedro, his best friend from the days of the university. The event was celebrated with dinner, drinks and women. Surprised, José receives the information that his friend is a subversive leader, long sought by the security agencies. The accusation of belonging to the same organization weighs on the young administrator Pedro's clandestine politics. He is subjected to torture to speak.
