Baird College's Mendenhall echoes with the footsteps of students heading home for Thanksgiving break and Robin Stone, who won't be going home, swears she can feel the creepy, hundred-year-old residence hall breathe a sigh of relief for its long-awaited solitude. As a massive storm approaches, four other lonely students reveal themselves to Robin: Patrick, a handsome jock; Lisa, a manipulative tease; Cain, a brooding musician; and Martin, a scholarly eccentric. Each has forsaken a long weekend at home for their own secret reasons. The five unlikely companions establish a tentative rapport, but they soon become aware of another presence disturbing the building's ominous silence. Are they the victims of an elaborate prank, or is the energy evidence of something genuine — something intent on using them for its own terrifying ends?

After experiencing a precognitive dream that shatters her engagement and changes her life forever, young California psychology professor Laurel MacDonald decides to get a fresh start by taking a job at Duke University in North Carolina. She soon becomes obsessed with the long-buried files form the world-famous Rhine parapsychology experiments, which attempted to prove if ESP really exists. Along with another charismatic professor, she uncovers disturbing reports, including a mysterious case of a house supposedly haunted by a poltergeist, investigated by another research team in 1965. The two professors and two exceptionally gifted Duke students move into the grand, abandoned mansion to replicate the investigation, unaware that the entire original team ended up insane... or dead.
