Two ghosts attend an engagement party, unseen by the other guests. One ghost, Dupont, is the father of the bride-to-be. He looks back on his marriage to her mother. His wife Annette was always very unhappy; business kept him away from home. The doctor recommended indulging her whims for furs and jewels. Then Uncle Émile suggested a trip to Paris. All went well until the day they went to the circus and saw the lion-tamer, Rodrigo the Conqueror. Rodrigo becomes Annette's lover ... and the second ghost... But wait a second. There's a third ghost at the party!
