81 natives and 46 Métis face charges following the "Riel Rebellion." Poundmaker is one of these men.

Poundmaker's trial begins on August 17 in a small Regina courtroom. Fifteen witnesses are questioned about his role in the events that the Cree call "the resistance" and the Canadians call "the rebellion." Poundmaker pleads "not guilty" to four counts of treason-felony in regard to the sacking of Battleford, the battle at Cut Knife Hill, the seizure of a supply train in the Eagle Hills, and a letter written to Louis Riel signed by Poundmaker and several other native leaders. The letter, a key piece of evidence, is used by the Crown to prove that Riel and Poundmaker planned to co-ordinate their efforts to overthrow the Canadian government.

At trial, Poundmaker's lawyer, F.B. Robertson focuses on his client's peaceful intentions. Robertson tries to show that Poundmaker never had absolute control over his camp. He argues the chief should not be held responsible for the actions of his tribesmen. A Catholic priest, Louis Cochin, testifies that Poundmaker did have considerable influence but he used his power to save lives. As for pillaging at Fort Battleford, one witness says the chief was seen with a bundle of goods, while another testifies the chief took nothing and tried to stop others from stealing. Robertson calls into question Poundmaker's signature on the letter to Riel. Did Poundmaker really contribute to the letter? Did he authorize his name to be signed on the letter?

Britton B. Osler, a member of the Crown's team of attorneys, steers the jury away from such questions. He says the letter reveals Poundmaker's treasonous intentions and reminds the jury of the chief's influence over his camp. Judge Hugh Richardson, the same judge who sentenced Riel to death, addresses the jury before they leave to deliberate. He ends by saying the law recognizes "no distinction between the red man and the white man." After just a few minutes, the jurors come back with a guilty verdict.

Before passing a sentence, the judge gives Poundmaker a chance to speak. Through an interpreter he delivers an impassioned speech saying he did everything he could to stop the bloodshed and declares his loyalty to the Queen. Judge Richardson acknowledges Poundmaker's peacekeeping efforts, but says the evidence against him is strong. The judge sentences him to three years in prison.
