Steve and Amy investigate paranormal claims at a haunted hotel called the Riverside Inn where the activity has gotten so bad that the owner says her employees and guests are scared to work and stay there. Through research, Steve learns that the property was acquired by Dr. John H. Gray in 1859 who went out looking for oil and discovered a spring instead and bottled mineral water in the basement. He started prescribing it to the locals, advertising it as "Gray Mineral Water" and made this place into a wellness sanitarium which was anything but since several people died from too much magnesium in the water. Meanwhile, Amy says she encounters Dr. Gray as a younger man, sees many of his sick patients, and meets two boys who drowned in the French Creek in 1979 who like to manipulate electrical energy. She also claims to see a scene of a man killing a woman she believes to be Doris Hatch who was murdered in the summer of 1953 by her boss and love interest William Turner.
