Arms and the Man takes places during the 1885 Serbo-Bulgarian war. Raina Petkoff is a young Bulgarian woman engaged to a famous soldier. One night, a Swiss voluntary soldier to the Serbian army, Bluntschli, bursts into her bedroom and begs her to hide him so that he is not killed. As the Petkoff family, their servants, and the soldier himself scramble to keep their secrets and preserve their ideals, they are forced to question their romantic notions about war, love, social class, and themselves.
