The miniseries chronicles the history of Acre, the last region to be annexed into Brazilian territory. For many years, the state—formerly part of Bolivia—attracted people from Brazil's Northeast and from abroad who left their hometowns in search of a better life through latex extraction. The relentless pursuit of new extraction sites took a toll on the natural environment, which was increasingly exploited in a predatory manner, and brought poverty to the region. The miniseries depicts this entire process, spanning a century, through three central figures: Galvez, Plácido de Castro, and Chico Mendes.
