Shaw has written a piece that takes place in Bulgaria around the turn of the 20th century, at the tail end of a war with rival Serbia. During a fight between the two nations, an enemy soldier, Bluntschli, ends up hiding in the room of a Major of the Bulgarian army to escape his enemy forces. She is instantly taken with him and his charm.

The war ends, and the Major returns home with his daughter's fiancé, who was also a soldier in the war. When Bluntschli returns, though, Raina is left with a difficult decision - to choose between the two soldiers.
