A group of paranormal experts is hired to investigate a supposedly haunted mansion owned by the Lauder family. The deceased owner, Avery Lauder, was a notorious magician with an interest in the occult who allegedly cursed the property before his death. The team, including a skeptical private investigator, a psychic medium, and various technicians, aims to rid the mansion of its supernatural forces so it can be transformed into a profitable bed-and-breakfast. Their sophisticated equipment detects strange occurrences, but initial findings reveal little more than eerie noises and unsettling atmospheres. As the group delves deeper into the mansion's sinister past, they uncover hidden rooms and secret passageways teeming with dark secrets.

Tensions arise as the investigators experience increasingly violent ghostly encounters, leaving them struggling to maintain their composure. The psychic experiences harrowing visions of Avery Lauder's malevolent spirit, while the skeptic begins to question his disbelief. Unexplainable phenomena escalate quickly, trapping the team inside the mansion with seemingly no way out. The paranormal experts realize they must work together to confront the evil forces at play, but their growing mistrust and fear threaten to tear them apart. The stakes rise when one of them faces a life-threatening situation, forcing the group to come up with a plan to survive the night and break Lauder's curse once and for all.
