Arms and the Man recap

During the Serbo-Bulgarian War, idealistic Raina Petkoff hides Bluntschli, a Swiss officer fighting for Serbia, when he escapes into her bedroom. His sweets, exhaustion, and practical account of combat challenge her worship of military heroism. Months later her fiancé Sergius returns as a celebrated cavalry officer, but he is privately disillusioned and attracted to the servant Louka. Bluntschli comes to return the coat used in his escape and proves far better than the officers at solving a logistical problem. His presence gradually exposes both couples' poses: Raina prefers his honesty to Sergius's performance, and Sergius cannot reconcile his engagement with his desire for Louka. Raina and Sergius separate. Sergius agrees to marry Louka, while Raina accepts Bluntschli after he learns she is old enough to make her own choice. The original romantic engagement gives way to two less conventional but more candid matches.

In Bulgaria during war with Serbia, Raina Petkoff and her mother Catherine celebrate news that Raina's fiancé, Sergius Saranoff, led a daring cavalry charge to victory. Raina treats the report as confirmation of her romantic ideals. That night a Serbian officer pursued through the town climbs into her bedroom and threatens her into silence. He is Captain Bluntschli, a Swiss mercenary who is exhausted, frightened, and more concerned with food than glory. He explains that Sergius's charge succeeded largely because the opposing troops had the wrong ammunition, undermining Raina's picture of flawless heroism. When Bulgarian soldiers search the house, Raina hides Bluntschli and lies to protect him. Catherine discovers him but joins the deception. They feed him, let him rest, and send him away disguised in Major Petkoff's old coat. Raina is intrigued despite continuing to speak as though her action belongs to a noble romance.

Peace has been made, and Major Petkoff and Sergius return home. Sergius is celebrated for his charge but has resigned his commission after learning that military authorities see him as an undisciplined amateur. He and Raina resume their elaborate courtship, each presenting an idealized self to the other. As soon as Raina leaves, however, Sergius flirts aggressively with Louka. She challenges his claims to nobility and hints that Raina may also have secrets. Bluntschli unexpectedly arrives to return the borrowed coat. Raina and Catherine try to prevent the men from learning that he was the fugitive they sheltered, calling him the chocolate-carrying soldier only in private. Petkoff and Sergius know Bluntschli from the campaign and welcome his professional expertise. When they need to plan a complicated troop movement, his practical solution exposes the contrast between real competence and Sergius's dramatic reputation. Catherine quietly restores the coat before Petkoff notices its absence, but a photograph Raina placed in its pocket threatens the concealment.

In the library, the household's secrets converge. Louka refuses to accept Sergius's treatment of her as a temporary amusement and presses him to act according to the equality he claims to believe in. Nicola recognizes her ambition and releases her from their understanding. Petkoff finds Raina's inscribed photograph in his coat, revealing that Bluntschli was the enemy soldier hidden in her room. Sergius, already compromised by his pursuit of Louka, can no longer sustain his idealized engagement. He and Raina acknowledge that they have both been performing roles and part without rancor. Sergius agrees to marry Louka. Raina drops her grand manner with Bluntschli and makes clear that she prefers his candor and capability. Believing her only seventeen, he initially treats her feelings as youthful fantasy; when the family corrects him and says she is twenty-three, he proposes. A message announcing his father's death and his inheritance of a large hotel business also reveals that the supposedly ordinary mercenary is wealthy and established. Bluntschli leaves to settle his affairs, promising to return for the wedding.

Bluntschli's return exposes the difference between the Petkoffs' romantic poses and their real desires. The inscription on Raina's photograph reveals that he was the enemy soldier she sheltered, while Sergius's pursuit of Louka makes his own engagement impossible to defend. Sergius and Raina release each other without lasting hostility. Louka insists that Sergius treat her as an equal, and he agrees to marry her; Nicola steps aside and turns his attention to a future business opportunity. Raina admits that Bluntschli's clear sight and practical nature attract her more than heroic display. He initially resists because he believes she is a sheltered girl, but proposes after learning that she is twenty-three. News that he has inherited his father's hotel business makes him an unexpectedly substantial match. The play closes with the two new engagements replacing the idealized pairing with relationships grounded in a more honest view of each person.
