Die schwarze Loo (1917)

About a gypsy who earns a living as a dancer in cheap barracks. Homeless, her performance is documented by a young and talented but largely unsuccessful composer. Before he dies, he leaves the gypsy dancer his artistic legacy, a previously unpublished composition. A little later, she becomes the wife of the orchestra leader, who completes the unfinished composition and wants to gain the sole glory for it.
