In the early 1970s, when Portugal was still under the authoritarian rule of Europe’s longest-lasting dictatorship, a handful of military officers decided to risk everything to try to free their country. In the shadow of the regime, they devised a coup d’état like no other. From that coup, a revolution blossomed: the Carnation Revolution.

50 years after that day of insurrection – April 25, 1974 – this documentary, which unspools like a historical thriller, aims to explore the multi-facetted events that would change the fate of an entire nation.
