Lieutenant Niko’s family insists he marry a chosen fiancée, but he falls for a beautiful baroness and travels to meet “his betrothed” disguised as his orderly, who impersonates him, only to discover that the baroness is in fact the intended bride. Meanwhile, the baroness and her maid swap identities in turn, leading to a cascade of mistaken identities and a lighthearted resolution when true matches are revealed.
