This is the diary of an extended trip across the Pampas, on the trail of Guillermo Enrique Hudson, aka William Henry Hudson. An enigmatic figure, full of paradoxes. He was an Argentine gaucho who became an English writer. He fought in the army against the “savages” but also defended them. He wrote obsessively about his native land, but never returned. In the twists and turns of the road, emerges a mix of documentary speculation, Argentine history, personal memory… and dreams.
