Guided by Mario Pergolini and Felipe Pigna, viewers will begin a journey through history. A journey through time and space whose objective is to repair those events that have been left out of museums and school textbooks. The four episodes of the first cycle of Algo Habrán Hecho extend between 1806, in a country that didn't even have a name, and 1852, when the Battle of Caseros ends the era of Juan Manuel de Rosas. Algo Habrán Hecho skilfully transits between fiction and the documentary genre, between drama and irony. Pergolini and Pigna will witness a time when betrayal and daring were paid for with life. They will cross the Andes Mountains with Gral. José de San Martín; they will accompany Mariano Moreno in his most tragic moments; with their hands, they will close the sad eyes of Manuel Belgrano.
