Buster Keaton Rides Again combines behind-the-scenes footage during the filming of The Railrodder with a retrospective of Keaton's work including scenes from The Butcher Boy (1917), The Frozen North (1922), Seven Chances (1925), and The General (1927). Keaton and Gerald Potterton, his director on The Railrodder, discussed and occasionally argued over gags in the film with the director concerned about the safety of his star. During the filming of The Railrodder, Keaton celebrated his 69th birthday. He also had the opportunity to meet fans across Canada.
