A simple country girl, Diana, unexpectedly learns that she is the illegitimate daughter of a noble duke, who, when dying, bequeathed her title and possessions. Everything would be fine, but the legitimate niece of Duke Theodore does not intend to simply cede what was unfairly bequeathed to Diana. But she is destined not only to taste the sweetness of noble life, but to fall in love with a beautiful aristocrat, who, to the surprise of Diana herself, reciprocates her feelings.
