"Tres días de julio" shows what happened in the city of Cádiz in the hours prior to the coup d'état of July 18, 1936, as well as what happened until the moment the Cadiz capital succumbs to the rebels on the morning of Sunday the 19th. The documentary features the participation of historians, relatives of victims of reprisals, and even some direct testimonies of people who lived those tragic days in their youth. The city and province of Cádiz are described as a fundamental piece in the coup because, when it failed in the main cities of the country, they began to play a fundamental role in the strategy followed by the rebels in the immediate Civil War.
