Tintin comes to Chicago to do an exposé on organized crime, and quickly captures Al Capone. He pursues gang leader Bobby Smiles to an Indian reservation where the gangster sets the Indians against Tintin. When Tintin discovers oil, the Indians are handed $25 and driven off the land within the hour. Tintin narrowly escapes lynching, a prairie fire, a train wreck, being tied to a railroad track, falling into a meat processor, and repeated kidnappings. He does so well cleaning up the mob that he receives a ticker-tape parade, and the thanks of a nation.
