Daru, a French-Algerian teacher, watches out of the window as two men—one on horseback, one on foot—approach the schoolhouse where he both lives and works. His students have not been to school for the past few days due to heavy snowfall, and he is thankful that the delivery truck was able to bring him supplies in advance of the blizzard. Daru hopes that the snow will end the terrible drought that has plagued the rocky plateau upon which the schoolhouse and the surrounding villages sit. The French government has been supplying him with grain rations to distribute amongst his impoverished students to help them through the drought.

As the two men arrive at the schoolhouse, Daru recognizes the man on horseback as Balducci, a gendarme—or French colonial police officer—whom he has known for years. The other man is an Arab prisoner, his hands tied together as he walks behind Balducci’s horse. Balducci keeps his horse walking at a slow pace, so the prisoner does not have to struggle too hard to keep up.

Balducci greets Daru warmly, and Daru invites the two men to wait inside while he takes the horse to the shed behind the schoolhouse. Once inside, Daru makes tea for everyone. He then asks Balducci’s permission to unbind the Arab man’s hands, to which Balducci agrees. When Daru asks about their destination, Balducci informs him that the schoolhouse—and Daru himself—were their goal. Balducci’s police department is small and understaffed, especially with a possible war brewing in the region, so headquarters has determined that Daru should transport the prisoner to Tinguit, the nearest town.

Daru assumes Balducci is joking and becomes increasingly distressed upon learning that he is serious. He argues that transporting prisoners is not his job. However, Balducci reminds him of the growing unrest in the villages, indicating that even civilians should step forward when needed in such an uncertain political climate. He reassures Daru that he is only responsible for escorting the man to Tinguit; afterward, he may return to his “comfortable life.”

Daru then asks Balducci what crime the Arab man has committed and whether or not he speaks French. Balducci explains that not only does the man not speak French, but he was also arrested for the murder of his cousin—likely over a petty grain dispute. Daru is repulsed by the crime and wonders aloud whether the police suspect that the Arab man is “against” French colonial rule. Balducci says it is unlikely but acknowledges that it can be hard to tell.

Before he leaves, Balducci encourages Daru to arm himself in case of a possible attack and leaves behind his pistol. Daru seems unconcerned, claiming that the location of the schoolhouse will allow him to see any potential enemies before they arrive. He also firmly tells Balducci that, while he is disgusted by the crime the Arab man committed, he will not turn him over to the French police. Balducci attempts to sympathize with Daru’s feelings, but he ultimately reminds him that they are both acting under orders. When Daru remains insistent, Balducci has him sign the transfer paperwork, tells Daru that his decision about what to do with the prisoner—and its consequences—is now his responsibility, and leaves the schoolhouse.  

After Balducci returns to the station, Daru goes into his room to nap and leaves the prisoner alone in the schoolhouse. He is dismayed to find the prisoner still present when he wakes up; Daru had hoped the man might take advantage of his slumber and escape. Now resigned to his circumstances, Daru makes food for both of them and begins speaking...
