Two twin brothers, Cláudio José and José Cláudio, definitively separate when one of them decides to leave for the big city. Years later, the second brother also started living in Rio de Janeiro. One night, he is attacked by three thugs, who kill his pregnant wife and leave him disfigured. In search of revenge, he follows in the footsteps of his brother, who will find himself working for a crime figure. And in pursuit of his discoveries, he began to wage his revenge against the criminals on the same level as he had been confronted.

In this follow up to the mondo success "Anaconda", the explorer Rolf Blomberg travels into Brazil's jungle in search of the terrifying Xavante indians. The expedition starts at the harbor town Belém at the end of the Amazon river, and continues inwards from there. In the ghost town Manaus, in the middle of the jungle, we visit the strange opera house (that is depicted in Herzog's Fitzcarraldo). On the river island Bananal in Rio Araguaya we meet the indian tribe Carajá and experience their daily life with bow hunting, fishing and dance rituals. at Rio das Mortes in Mato Grosso we win the friendship of the terrifying Xavante indians. After a visit to Rio de Janeiro the expedition continues to the Atlantic coast and Portaleza whose population of fishermen still use a primitive fishing raft, "jangada", for their long and dangerous hunting journeys at sea.
