Since the 1930's the FBI have secretly conducted investigations into the Supernatural, but to this day hard evidence of their existance is still weak. Various divisions within the FBI encounter the paranormal more frequently than they could ever know, but before they begin to suspect their cases are handed over to divisions specially equipped to deal with the World of Darkness.

This units work takes them closer to the paranormal, some suspect, some think they know, others choose to ignore it. But someone seems content for them to continue their work, unabated but monitored, gradually uncovering some unearthly truths.
