The Ghost Hunters are back! Original founding member, Grant Wilson, returns with a new team of investigators. In their very first case, Grant is contacted by the principal of a century-old high school in Pocatello, Idaho that has long been rumored to be haunted. During her tenure, the principal has dismissed many of these rumors as mere urban legends. However, when the school's security cameras capture an unexplained electrical disturbance followed by what appears to be a ghostly apparition in the hallway, she begins to fear there may be some truth to the local legends. Might Pocatello High School truly be haunted? Or is there some other explanation? The Ghost Hunters are on the case to investigate.

The team comes to the aid of a woman in Hanover, PA, who has been tortured for years by unexplained activity in her home. After repeatedly getting scratched and even being thrown down the stairs, Deanna and her husband, Tom, have finally decided to flee their home for good. But before she leaves, Deanna needs closure, and it's up to the Ghost Hunters to bring it to her. Then, Grant returns to the St. Augustine Lighthouse, site of some of the most compelling paranormal evidence ever captured in Ghost Hunters history when the team is summoned to investigate a reported increase in paranormal activity, both in and around the undeniably haunted landmark. Is paranormal activity at St. Augustine truly heating up? Or is the Lighthouse's haunted reputation merely activating the imaginations of staff and visitors?
