Blithe Spirit is a comic play concerning socialite and novelist Charles Condomine, who invites the eccentric medium and clairvoyant, Madame Arcati, to his house to conduct a sance, hoping to gather material for his next book.

The scheme backfires when he is haunted by the ghost of his annoying and temperamental first wife, Elvira, following the sance. Elvira makes continual attempts to disrupt Charles's marriage to his second wife, Ruth, who cannot see or hear the ghost. A witty and sophisticated look at social mores in 1930's Britain.
