At the world's southernmost edge, the breathtaking landscapes of Tierra del Fuego stretch seemingly untouched to the horizon. Yet this beauty holds a turbulent history. Filmmaker Michaela Grill journeys through the region in search of traces of Indigenous cultures profoundly altered by centuries of colonization. Bringing together landscapes, Indigenous voices, and accounts from the past, When Fire Turns to Ash reveals a place where history is still present – in its people, its memories, and the land itself.
