Morgan City, La., is experiencing a disconcerting spike in emergency calls related to encounters with ghosts from the bayou city's turbulent past. Police Chief James Blair calls upon a team of paranormal experts to investigate the city's rise in bizarre activity. The team is led by Lousiana native Jereme Leonard, former FBI agent Ben Hansen and psychic medium Sarah Lemos. With the help of local historian Diane Wiltz, the team digs into the area's haunted history and begins the crossing-over process for some of the spirits wreaking havoc on the small community. Learning that the hauntings have spread throughout the area, the team begins working with other police departments to get to the bottom of the ghostly infestation of St. Mary Parish.
