Alone in a Haunted House

This spine-chilling and deeply thought-provoking documentary follows the exploits of paranormal investigator Joshua P. Warren, who, in an attempt to prove or disprove once and for all the existence of apparitions and spirits, spends a night in a home known to be haunted. What transpires is positively spooky as Warren (who wrote How to Hunt Ghosts) uses tools such as infrared scanners and electrostatic generators to arrive at the truth.
