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.

Poor girl sells matches with brief flickering flame reflecting her span of life & dreams.
