The Unfinished Dance(1947)

Meg, a young ballet student, idolizes the school's top ballerina, the shallow Ariane Bouchet. Meg is distressed when she learns visiting prima ballerina Darina rather than Bouchet will play the lead in the school's production of "Swan Lake." So on opening night, Meg arranges an accident which nearly kills Darina and ends her dancing career. As a result, Bouchet becomes a star, while Meg is torn with guilt. This is a remake of the 1937 French film "Ballerina", based on a short story by Paul Morand.
