In the sequel to the 2010 movie, the found footage concept is out and franchise building is in. Instead of focusing on the preacher and camera crew, this time the plot revolves around the possessed/possibly crazy Nell (Ashley Bell) who is taking refuge in a New Orleans group home after the events of the last movie. The demon Abalam seems to be taking an interest in Nell and everyone around her because a piece of him resides in her still. So just as dark shadows and demonic contortions are happening all around her, a little exorcism (with some voodoo thrown in for good measure) is needed.
The trailer hints at some mythology taking shape with the Abalam concept - and without some of the ambiguity of the first movie - so this is likely the first of many more "Lasts" if the box office treats them right.
