La Mort du Cygne (1937)

As its title indicates, La Mort du Cygne is set in the special world of the ballet. Young dance student Rose Souris idolizes her teacher-role-model Mademoiselle Beaupré, and will do anything to help Mademoiselle Beaupré further herself. Thus, when rival ballerina Nathalie Karine lands a much-coveted role, Rose arranges an accident causing Nathalie to break her leg. The girl comes to regret her rash behavior when it appears as though Nathalie will never dance again.
