Mankind’s greatest fear is also its greatest obsession. What awaits when we shuffle off the mortal coil of this world? We all have our beliefs based on faith or science, but both struggle to provide a tangible answer. Perhaps it is possible to prove the existence of the soul, to prove it goes on after death.

Following the violent death of his parents, Jeff Granger seeks reassurance that they have moved on. After recording what he believes to be his mother’s voice at the site of the accident, Jeff’s obsession throws him into paranormal research. Realizing that most people are doing it just for fun, Jeff forms his own group. He is joined by Debbie Gillerson, a schoolteacher; Aaron Presley, a mortician; and Michael Pacheco, a grocery store manager. Even though they are all investigating the paranormal for very different reasons, they are all trying to fill an emptiness in their lives. The deeper they probe paranormal theory, the darker their results.

The only way to truly test the Death Theory, as theorized by Aaron, is to monitor a person’s energy at the moment of death. Horrified by the immoral and unethical application, the group dismisses the theory. A darkness seems to follow their investigations, and the police become involved. A former colleague of Jeff’s, a self-proclaimed demonologist, believes a demonic force is attached to the group. The police are not so sure. Evil comes in many forms, as the small group is about to discover.
