1921, in de buurt van Parijs. Op het kasteel van Marguerite Dumont is het feest. Net als ieder jaar heeft de eigenares van het kasteel ten voordele van een of ander belangrijk doel een hele zaal vol muziekfanaten bijeengebracht. Over de vrouw is niet echt veel bekend behalve dat ze schatrijk is en haar hele leven in het teken staat van die ene passie: muziek. Ze heeft weinig zangtalent, maar heeft zelf het idee dat ze heel goed kan zingen...
Nee, helaas is Marguerite nog niet beschikbaar op Netflix in Nederland.
