Haunted by atrocities he committed as a black-ops soldier, Jonathan Dekker hides in the Amazon with the Kayapo tribe—until land raiders massacre the village that sheltered him. To buy the tribe's land and save them, Dekker returns to the world he fled, entering Brazil's brutal vale tudo circuit alongside a blind fighter, Lusia, and a washed-up manager, Rourke. Their success draws the attention of both a Rio crime lord running a death-match tournament and Securecorp, the corrupt military contractor Dekker betrayed—which sends his former best friend, Alex Mason, to kill him. To win the money, survive the hunt, and expose the truth, Dekker must conquer the undefeated champion Carlito and finally face the brother he once trusted.
