When fires sweep through the rainforest near their property along the Parana River, a poor tobacco-farming family goes on high alert. The head of the family, João, correctly suspects the fire is a result of slash-and-burn tactics by ruthless land-grabbers intent on acquiring the farm he shares with his daughter Vânia and her partner, Jara. Help arrives in the form of the enigmatic Kaí, who emerges from the jungle with the grace of a jaguar. But the violence of the land-grabbers' assault catches Kaí and the farm dwellers off guard. The men shoot Jara and force João to sign over his land just before killing him and kidnapping Vânia. Undetected, Kaí goes on the offensive. Using his animal-like abilities, he rescues Vânia, retrieves the bogus bill of sale, and thwarts a counter-attack by the band of mercenaries, all without taking a life. But with the hornet's nest now stirred, Kaí, Vânia and Jara must decide how far they will go to preserve the farm and they vanishing way of life.
