The purpose of the film is to provide knowledge of the Institutional Revolutionary Party's foundation and origins which has been a witness to and protagonist of Mexico's history. Likewise, this program shows us how it became the hegemonic party and pillar of political and social conformity in our country and which maintained presidential power for decades. Through the testimonies of some of its directors and militants, as well as political analysts and journalists we see how the PRI abandoned the democratic process within its ranks and because it turned more inward, it could not become the core of political life in the rest of the country. Spectators will notice how, throughout the country's history, no one can understand contemporary Mexico without understanding the PRI.—Clío TV
