The self-management experience of the workers of the Numax factory in Barcelona (Spain), at the end of the seventies, was included in a documentary that they themselves decided to entrust to the filmmaker Joaquim Jordà at the moment when the factory were about to close. It was titled "Numax presents..." (1980). Those images, recovered, together with the situation in which those same workers are so many years later, lead us to reflect on the last and intense decades that have been lived in Spain, to discover the fragility of youth ideals and offer a history of the political transition from dictatorship to democracy.

La experiencia autogestionaria de los trabajadores de la fábrica Numax, a finales de los setenta, quedó recogida en un documental que ellos mismos decidieron que se hiciera, y que encargaron a Joaquim Jordà en el momento en que estaban a punto de cerrar. Se tituló «Numax presenta...» (1979). Aquellas imágenes, recuperadas, junto con la situación de los trabajadores tantos años después, llevan a reflexionar sobre las últimas e intensas décadas que nos ha tocado vivir, para descubrir la fragilidad de los ideales de juventud y ofrecer "una historia de transición" con minúsculas.
