The next day, the boys encounter the same group of men led by J.J. harassing a girl named Jo from the protest, at the pizza parlor, after she demands they tell her about her father's whereabouts.

Jo comes to the boys later at the pizza parlor and explains that the men are under the employ of Jack Harding, an industrialist who is illegally dumping toxic contents into the Native American reserve.

The boys follows the men to sneak into Jack's waste management and overheard his conversation with the Mayor about corruption and find Charlie imprisoned.

During the dance, Jack and his men attack them once again until the boys and Native Americans fight them off with the help of Mori, who is suspicious about his grandsons' activities.

The Douglas boys get the information to find where Jo is being held hostage, drive out to rescue her and return before the court case is dismissed and all of Charlie's hard work accounts for nothing at all.

Charlie punches Jack, admits his mistake and hands the real evidence to the EPA representative who resolves the case and finally shuts down the company producing the waste.
