Portal to the Void

Deep in the forests of Oregon rests a little town named Riverton. During summer vacation, Robert and his family soon learn that there's more to the town than just its long history. Ghosts and spirits are around every corner, and a sinister force is at play. All of which are connected through a portal that leads to another realm called "The Void."
After some research and near-death experiences, Robert, his sister, and two cousins discover the truth about the small town. To keep everyone they love safe, they will need to close the portal. However, their heroic acts won't be successful unless they defeat the evil spirits protecting it.
