A young man of indigenous ancestry leaves, where he lives in the North, to rediscover the history of his people in the heart of South America. As he rediscovers the memory of his ancestors, he dreams with the history of the conquers and the decadence of white men. In a transformative journey of nature, men and light, there is an intersection between these multiple universes and an essay on the complex territories and people of the Americas. "Light in the Tropics" is a triptych about the march of humanity through time and space.
