Tribeca’s closing night selection this year is a riveting eco-doc that profiles Indigenous rights activist Juma Xipaia (the first female Indigenous chief of her people in the Middle Xingu) and her husband Hugo, who heads up a government special ops team that locates and shuts down illegal mining operations in Brazil’s Amazon region.

Richard Ladkani’s doc unfolds like a Costa-Gavras political thriller; early on in the film we see harrowing footage of Juma participating in a protest outside of the National Congress Palace in Brasilia where riot police suddenly fire a fusillade of live rounds into the crowd. A distraught Juma kneels beside a tribal activist who appears to be gravely wounded, pleading for him to respond (he doesn’t) until fellow demonstrators pull her away, out of the line of fire.

Juma, we learn, is no stranger to the threat of violence; she has survived a number of assassination attempts over the years and continues to be under threat. Yet she soldiers on, fighting outside and (eventually) inside of Brazil’s political system for her people…as does her husband (Juma and Hugo form an eco-warrior power couple).

Ladkani follows Hugo and his team on several missions; these scenes play like they are straight out of an action film, but instilled with an all-too-real sense of danger (the illegal miners are frequently armed and rarely happy to see the government commandos). Mining has been prohibited since Brazil’s Federal Constitution of 1988, as it not only wreaks havoc on the Amazonian ecosystem, but has a number of negative health effects on the Indigenous peoples of the region.

Ladkani’s film is slickly made and hypnotically photographed, but doesn’t pull any punches regarding its heavy subject matter. When you consider 10,000 acres of the Amazon rainforest are destroyed every day, the sense of urgency here  becomes all the more palpable.
