An orphan named Marie has been raised from infancy
by a French army regiment whose soldiers love her for her beautiful
songs, her cheerfulness, and her beauty. She has fallen in love with the
handsome Tonio, who joins the regiment just to be near her.
When her aunt, the Marquise of
Berkenfield, discovers her by chance while traveling in the region, she
demands that Marie be returned to her family to take her rightful place
as a noblewoman, married to a nobleman. An unraveling chain of family
secrets and the sudden appearance of Tonio and the entire regiment
scandalize Marie's stuffy in-laws-to-be and derail her arranged wedding.
