There are 85 million cows in the Brazilian Amazon, which means three cows for each human dweller grazing today and area that was once forest. Less than fifty years ago, in the 1970s, the rainforest was intact. Since then, a portion the size of France has disappeared, 66% of which transformed into pastures. Much of this change is a consequence of government incentives that attracted thousands of farmers from southern lands. Cattle ranching became an economic and cultural banner of the Amazon, forging powerful politicians to defend it. In 2009, there was a game changer: the Public Prosecutor's Office sued large slaughterhouses, forcing them to supervise cattle supplying farms.

In the north of the state of Pará is the largest block of protected forests in the world; an area of ​​Amazon rainforest the size of the UK and home to a multitude of stories. Indigenous people, ranchers, squatters, quilombolas, businessmen and politicians reflect in their own way the impacts of the possible expansion of the BR-163 into the forest, as far as the border with Suriname. The highway project was created at the time of the military dictatorship, and until today as a shadow over the region. But this is not a movie about a road. It is a film about the abysses that separate those who share the same land.
