Buster Keaton plays Johnny Gray, a Southern railroad engineer who loves his train engine, The General, almost as much as he loves Annabelle Lee (Marion Mack). When the opening shots of the Civil War are fired at Fort Sumter, Johnny tries to enlist -- and he is deemed too useful as an engineer to be a soldier. All Johnny knows is that he's been rejected, and Annabelle, thinking him a coward, turns her back on him. When Northern spies steal the General (and, unwittingly, Annabelle), the story switches from drama and romance to adventure mixed with Keaton's trademark deadpan humor as he uses every means possible to catch up to the General, thwart the Yankees, and rescue his darling Annabelle -- for starters. As always, Keaton performs his own stunts, combining his prodigious dexterity, impeccable comic timing, and expressive body language to convey more emotion than the stars of any of the talkies that were soon to dominate cinema.
