Amid the wedding preparations in the town square, an irate Doctor Coppélius arrives to denounce the union and heap some serious scorn upon the couple to be married. He tells the townsfolk that Franz and Swanilda ridiculed him and destroyed his life’s work. He demands justice and restitution.
Dismayed at having caused such upset, Swanilda begs for Doctor Coppélius’ forgiveness and invites him to the wedding. Coppélius is touched, and because he’s spent a good portion of the morning drinking “magic potions,” manages to forget how much he hates Swanilda, Franz, and almost everyone in the village.
Alas, Doctor Coppélius says he cannot attend the wedding because he lacks the proper attire. The village tailor, Mudjik, steps forward and offers him a new outfit for the nuptials. The widow Lustige (Swanilda’s mother) takes Doctor Coppélius by the arm and begins to flirt with him. She, too, has consumed enough “magic potion” to overlook Doctor Coppélius’ attempts to murder her future Son-in-Law. Doctor Coppélius forgets his dolls and loneliness and joins in the festivities.
There is rejoicing in the village as Franz and Swanilda are married, thereby fulfilling the prophecy promised by the legend of the stalk of wheat. (Not really. Dumb and Dumber didn’t hear the wheat rattle, but the burgomaster tells the story differently.) The townspeople celebrate the union of Swanilda and Franz late into the night. Doctor Coppélius, brimming with good will and forgiveness, blesses the marriage. The doll-sized hole in his heart has been filled with the love of his new friends.
