Grave Encounters (2011) on Netflix

Five people. One abandoned mental hospital. Fourteen cameras. One locked door. Hundreds of barred windows. You will be unprepared for the horrifying scenes unfolding upon Lance Preston and his crew. Abandoned years ago but never demolished, the Collingwood Psychiatric Hospital stands to this day. Reports flow of apparitions, ghosts, spirits, noises and hauntings. This attracts young producer Lance Preston of the "Grave Encounters" reality series crew to the location in the hopes of shooting their next episode. As instructed, Kenny the caretaker locks the crew inside after the walkthrough and his own interview, and chains the door shut. They are alone in the building and quite literally imprisoned within it's walls. But this is no mere building; It has a history. AND and attitude! With cameras from the crew and the Static Cameras recording every angle of the sheer terror on film you will be clutching your seat as the crew clutch their lives and their sanity. Jerry Hartfield, producer: "What you are about to see is not a movie. We assembled this from some 76+ hours of raw Mini TV sourced footage That was shot for Lance's show. It has not been manipulated in any way; it's just raw footage that't been edited strictly for timing."
