Capitalizing on the Spiritualism craze of the late 1800s, business is booming for the Glass Brothers Paranormal Investigation, Inc. Despite the three brothers' bickering, exposing fraudulent psychic mediums is proving profitable business, even if it's ruffling feathers of the elite members of society. Everything changes, though, when a failed magician discovers a chest containing a powerful, malevolent spirit. Calling itself Lenore, the spirit promises the magician fame in exchange for a human vessel to open a door into the spirit world. As the Glass Brothers connect the recent string of missing women to one another, their path eventually leads to the magician's stage and the battle to keep the spirit door closed.
