Grant and the team come to the aid of a single mother, Susan, and her young son who are afraid that spirits in their turn-of-the-century Victorian house in Willimantic, CT may be a threat to their safety. Could the haunting be the original builder and owner of the home who passed away in the house decades ago? Or is something more sinister? Meanwhile, Kristen experiences strange phenomena while investigating claims of a child's voice in an upstairs bedroom. Following night one, Grant is fairly certain he knows what's going on and devises an innovative tactic requiring a choreographed effort by the entire team to test his theory. Will the team manage to pull it off and get Susan and her son the answers they need?

The Ghost Hunters head down south to Louisiana to help a woman who is worried that the sugar cane plantation that has been in her family since after the Civil War, may literally be haunted by its troubled past. With countless deaths on the property over the plantation's 200-year history, the list of spirits that may be present at the large estate is seemingly endless. Maureen has fond memories of growing up at the St. Joseph plantation, but recent sightings of a bloody apparition now have her and her staff petrified. Could it be the ghost of a former plantation doctor well-known for performing gruesome surgeries? Grant and the team investigate the expansive 2500-acre estate, from the huge mansions to the former "slave shacks." Since the plantation has never been investigated before, Grant employs a special technique to help build trust with any intelligent entities.
