Through the files of Cuban cinema news program Noticieros ICAIC Latinoamericanos, the documentary shows the most relevant events of the second half of the 20th century as seen by the documentary filmmakers of the island. During three decades and under the general direction of Santiago Álvarez, these moviemakers witnessed almost everything: from the shivers of the Cold War to Bola de Nieve’s piano solos; from the discovery of the killing fields in Cambodia to the Carnation Revolution in Portugal. In 2009, the original negatives of Noticieros ICAIC Latinoamericanos were declared part of the “world memory” by UNESCO.
