A group of children of various races from the school go to town for ice cream and are refused service and then abused and humiliated by Bernard Posner (David Roya), the son of the county's corrupt political boss (Bert Freed), and his gang. This prompts a violent outburst by Billy. Billy goes through a Navajo Indian iniation where he gets bitten purposely by a deadly rattlesnake, so that he would become the blood brother to the snake, which he does survive. Meanwhile, Susan loses her unborn child, when the horse she was riding, stumbles on a rock, causing her to fall off the horse. Following an incident, involving Jean, Billy gives Bernard a choice of either receiving a cut arm, or to drive his Corvette into the lake, in which Barnard does the latter. Later, Jean is raped by Bernard, who also murders a Native American student. Billy confronts Bernard, whom he catches in bed with a 13-year-old girl, and sustains a gunshot wound before killing him with a hand strike to the throat. After a climactic shootout with the police and pleading with Jean, Billy Jack surrenders to the authorities in exchange for a decade-long guarantee that the school will be allowed to continue to run with Jean as its head. As Billy is driven away in handcuffs, a large crowd of supporters raise their fists as a show of defiance and support.
