Ghost Hunters International was a spin-off series of Ghost Hunters that aired on Syfy. The series premiered on January 9, 2008. Like its parent series, GHI was a reality series that followed a team of paranormal investigators; whereas, the original series primarily covers only locations within the United States, the GHI team traveled around the world and documented some of the world's most legendary haunted locations.

In 2017 Adam Ellis captured the image of a ghost child in his New York City apartment documenting his haunting on social media under the hashtag DearDavid. Now Adam and two of his friends are on a mission to help others understand and escape their own paranormal nightmares.
