Traveling through the breathtaking landscape of the Purús River, located in the far north of the Ucayali department, we find 45 communities from 13 different ethnic groups living along its banks in close and daily connection with the river and with nature. Guided by Alfredo del Águila, a 45-year-old Sharanahua indigenous man and leader of the Santa Margarita community, we journey through his stories, anecdotes, and encounters with other people, such as the Shipibo and Yine park rangers at the border checkpoint on the Tahuamanu River, who are responsible for protecting one of the territorial reserves where uncontacted people live freely.
