Betrayed
Steve and Amy investigate a family in Southern New Jersey who believes their house is haunted by an evil entity. Through research, Steve says he discovers evidence that in the late 1800s, a nearby "health spa" that was really a sanatorium was run by an allegedly insane doctor named Dr. Smith who believed he found the fountain of youth. Steve also learns about a German immigrant, Louis Roesch who came to town in the 1860s and was betrayed by his people because there was no civilization here. Meanwhile, Amy says she encounters a monstrous shadowman in the basement who attempts to harm the living including herself. Also Amy claims to come into contact with the previous owner, Louis Brunk who died in the home and the two of the six children of the Roesch family.
The Beast
Steve and Amy investigate a family who say they are getting sick in their family home and uncover what they feel is attacking their daughter with special needs. During the investigation, Steve uncovers past evidence of a fatal train disaster in 1907 caused by a flagman that occurred on the property which was the Rudd farm. The property history allegedly includes two men who threw dynamite inside a Black Methodist Church along with 4 men from the KKK who burned down the school next to it. Meanwhile, Amy says she confronts a beastly, dog-like apparition that she fears can kill anyone who gets in its way and an old man who was beating an 8-year-old boy named Elmer who once lived here.
