Available Oct 5. Tensions between the government and the students reach a boiling point. President Diaz Ordaz asks Luis Echeverria to arrange a meeting with the students. But Emilio Martínez Manatou, Chief of the Presidential Office and contender in the presidential race, seeks to take the lead in this negotiation. Thanks to his closeness with Dean Barros Sierra, he succeeds. Barrientos aims to cancel out Manatou's gains through an operation that creates, in the eyes of the President, a sense of "chaos" in the country. Beto knows that Alicia has discovered his identity and tries to take her out the city before her life is in danger. But he soon realizes that Barrientos' eyes are everywhere.
