Description: Argentina, 1880. A group of exhausted soldiers sails down the Pilcomayo River. A man at the head of the group hesitates. It's Colonel Luis Jorge Fontana. The lives of many men depend on his decision, and he knows it very well. The territory of a country isn't something that falls from the sky: the borders drawn on maps are the product, at some point in history, of the will and determination of a few men; and Fontana was one of those men.
