The ghost-hunters arrive at the house of the wealthy heiress, Madame Pernelle, and discover that the house is haunted. The sisters decide to take a closer look at the room where the ghost is believed to be living. They discover a drawer in the bedroom, which they believe to be the key to the room's mysterious power. The ghost's voice is heard in the background, and the sisters decide that it must be their husband. They decide to seal the balcony, so the ghost will not be able to enter the house.
