Some time during World War I, Doughboy (Charlie Chaplin) begins his service in the war amongst "the awkward squad" a group of American soldiers.[3] He is bow-legged, unbalanced, and uncoordinated during bootcamp in contrast to the other soldiers who all have excellent coordination. He does move on to the front in France though, amongst the shells and trenches, and bunks amongst comrades (Sydney Chaplin). Doughboy is charged with guard duty and begins daydreaming of bars, cities, and home before being dismissed back to his bunk.
News/mail for soldiers is brought out for the soldiers, but there is nothing for Doughboy. Though his fellow soldiers offer him food from their mail he refuses and walks out to find there is a package for him; Limburger cheese and incredibly hard crackers. Due to the pungent smell of the cheese, he decides to throw it over the trench, hitting the Germans, rather than eat it.
Later, Doughboy struggles to sleep in waist high water, with his comrades all sleeping with no particular trouble in the conditions. In the morning, they are given the order to advance over the top. After hyping himself up against a backdrop of exploding artillery, Doughboy somewhat reluctantly goes over and manages to capture the enemy trench and 13 German troops the same as his identification number. Doughboy becomes much more confident after these events, and is no longer frazzled by the artillery or scared to take shots over the trench.
Doughboy volunteers for a secret mission and is advised that he may not return. His mission is to infiltrate enemy lines, disguised as a tree. When one of his comrades is captured spying on the enemy, Doughboy helps him to escape and is chased by a large German soldier (Henry Bergman) into the woods. Losing his tree disguise he is able to escape to a bombed out building wherein he meets a French girl (Edna Purviance) who tends to his wounds. Shortly after meeting, the large German soldier finds them. Both the French girl and Doughboy run, however the French girl is caught and arrested for aiding the Allies.
Before the French girl is assaulted by a German soldier, Doughboy manages to save her. Then the Kaiser shows up and Doughboy, disguised as a German officer, saves his comrade from capture again. All three of them now disguised as German officers chauffeur the Kaiser and his allies towards the Allied front. At the front they are greeted with applause and praise from the Allied troops.
Doughboy then wakes up back at bootcamp, revealing all was his dream.
Shoulder Arms proved to be Chaplin's most popular film, critically and commercially, up to that point. A review in the October 21, 1918 New York Times was typical:
"'The fool's funny,' was the chuckling observation of one of those who saw Charlie Chaplin's new film. Shoulder Arms, at the Strand yesterday—and, apparently, that's the way everybody felt. There have been learned discussions as to whether Chaplin's comedy is low or high, artistic or crude, but no one can deny that when he impersonates a screen fool he is funny. Most of those who go to find fault with him remain to laugh. They may still find fault, but they will keep on laughing."
The film was very revolutionary for its time, introducing a new genre of comedy. Previously, films had treated war as a serious subject. This is believed to be the first comedy film about war.[4]
