Coppélia is a sentimental comic ballet of the romantic genre that premiered in Paris. In the story, a woman named Swanhilde pretends to be a lifelike doll created by Dr. Coppelius, as the man she loved, Franz, had fallen in love with the doll. She pretends that the doll has come to life and ultimately saves Franz's life from the inventor.
"Doll that was tragically brought to life without a soul and forced to be a demon."
