Is time just an illusion?

Charles never believed the ghost stories about the old factory. As a psychology student, he understood the spooky tales told by the midnight workers were just the products of overtired minds. But when his company is hired to clear out the derelict old building, a small group of night workers become stranded in the isolated, mist-shrouded complex. Charles decides to conduct a psychological experiment to see if he can re-create the ghostly effects people have seen and heard over the years. But the experiment goes horribly wrong and something inexplicable happens. Now Charles is starting to believe...as he finds himself fighting for his sanity and his life.
