In 1956, one year after the self-styled "Liberating Revolution" dictatorship has deposed Argentine president Juan Perón in a coup, a civil-military insurrection fails in its attempt to take on power in the name of peronism. In retaliation, in a vacant lot of the city of José León Suárez (province of Buenos Aires), several civilians accused of being part of the uprising are illegally shot by the dictatorship. However, seven people manage to survive and tell their story to the world.
