A tribute to Santiago Álvarez, a great innovator in the language of Cuban newsreel images, presented by the ICAIC over the course of thirty years. This unique figure in Latin American cinema is reconstructed. Told as a game of Chinese boxes (documentaries within documentaries, authors within authors, images within images), Álvarez's obsession is revealed to be identical to that of his disciples: to confront the reality of Cuba with other realities, staging aesthetic operations that are nevertheless political operations, always in favor of the Revolution.
