When writer Charles Condomine decides to hold a séance as research for a new mystery novel, he has no idea that he’ll end up being haunted by his now-deceased first wife, Elvira—a ghost that only he can see. Not surprisingly, Charles’ second wife, Ruth, isn’t amused by his claim that Elvira is in the room, and the comedy quotient rises to a fever pitch when Madame Arcati, the daffy medium who conducted the séance, tells Charles she has no idea how to send this blithe spirit back where she came from!
