The Brink [DVD] [2003]

A brilliant engineering student discovers Thomas Edison's blueprints for a device designed to allow the living to communicate with the dead, only to find that you never know who is waiting on the other side in a frightful tale of supernatural malevolence. Megan Goss has discovered the designs for a device that would revolutionize our entire concept of death, and she's determined to test the machine with a help of a few close friends. Upon gathering the materials needed to assemble the communicator, Megan invites a group of fellow students to an abandoned house to assemble it and take it for a test run. But the house they have chosen isn't a place where spirits rest quietly, because years ago a troubled family brutally murdered one another within its walls and now a terrifying force of evil lies in waiting for someone to bridge the gap between the physical and spiritual realms. Now, as the switch is flipped and the spirits sense a path to freedom, mankind's darkest fears about the afterlife are about to become a terrifying reality.~Jason Buchanan
