Based on an operetta by Kálmán, Emmerich "Das Veilchen vom Montmartre" which in turn was inspired by Puccini's "La bohème". This is a story of three struggling artists: a painter, a poet, and a composer, living in a bohemian Montmartre district of Paris. They help a poor flower girl, Violette, to find shelter, when she is thrown out by her landlord.
