Dancer in the Dark (2000) on Netflix

Selma is a Czechoslovakian immigrant, a single mother working in a factory in rural America. Her salvation is her passion for music, specifically, the all-singing, all-dancing numbers found in classic Hollywood musicals. Selma harbors a sad secret: she is losing her eyesight and her son Gene stands to suffer the same fate if she can't put away enough money to secure him an operation. When a desperate neighbor falsely accuses Selma of stealing his savings, the drama of her life escalates to a tragic finale.
