The title evokes that of the book by Senator Amílcar Vasconcellos about the "semi-coup" of February 9, 1973, and the film recounts the tense relations that developed between the different military forces, and in particular, the actions of Rear Admiral Juan José Zorrilla, who deployed war units by air, land and sea to stop the military insurrection of that year, comparing the sometimes contrasting positions of the different interviewees, without forcing conclusions on points that are open to discussion.
