The story of Coppelia concerns a mysterious and faintly diabolical inventor, Doctor Coppelius who has made a life-size dancing doll. It is so lifelike that Franz, a village swain, is infatuated with it, and sets aside his true heart's desire, Swanhilde, who in Act II shows him his folly by dressing as the doll and pretending to come to life. The festive wedding-day divertissements in the village square that occupy Act III are often deleted in modern danced versions, though one of the entrées was the first czardas presented on a ballet stage.
