Un extraño enemigo - Season 1 Episode 1

July 1969. The National Security Directorate (DNS), headed by Major Fernando Barrientos, is in danger. The regent of Mexico City, Alfonso Corona del Rosal, wants to get rid of the Directorate and thereby weaken one of his main adversaries in the presidential succession: the Secretary of the Interior, Luis Echeverria. In an act of survival and political revenge, Barrientos intends to save his Directorate and support Echeverria, his direct boss, as the sole successor of Gustavo Diaz Ordaz. The main point of his strategy is tied to the incipient student movement that is trying to improve the lives of students and workers. Barrientos has taken the task of creating the perception that these young men are a real threat… and then repressing them violently, thus getting his boss to a better position in the eyes of the current President.
