Charlie is in boot camp in the "awkward squad." Once in France he gets no letters from home. He finally gets a package containing limburger cheese which requires a gas mask and which he throws over into the German trench. He goes "over the top" and captures thirteen Germans ("I surrounded them"), then volunteers to wander through the German lines disguised as a tree trunk. With the help of a French girl he captures the Kaiser and the Crown Prince and is given a statue and victory parade in New York and then ... fellow soldiers wake him from his dream.

Charlie's Tramp character finds himself at a circus where he is promptly gets chased around by the police who think he is a pickpocket. Running into the bigtop, he is an accidental sensation with his hilarious efforts to elude the police. The ringmaster/owner immediately hires him, but discovers the Tramp cannot be funny on purpose, so he takes advantage of the situation by making the Tramp a janitor just happens to always in the Bigtop at showtime. Unaware of this exploitation, the Tramp falls for the owner's lovely acrobatic daughter, who is abused by her father. His chances seem good, until a dashing rival comes in and Charlies feels he has to compete with him.
