In the north of Argentina, a green patch of immense dimensions is discovered: 150,000 hectares of forest belonging to the La Fidelidad ranch. Its owner, an Italian named Roseo, is brutally murdered by landowning mafias. Before this natural paradise is dismantled, a group of NGOs achieve something unprecedented in the country: the construction of a National Park through fundraising, which we know today as El Impenetrable National Park.
