With old enemies gone, Abbie and Crane are apparently moving on with their lives. However, the discovery of a mysterious tablet shows that there may be a new dark prophecy surrounding our Witnesses. The two team together, with the help of an old amulet, and continue their epic takedown of the forces of evil. In this modern-day twist on Washington Irving's classic, Ichabod Crane is resurrected and pulled two and a half centuries through time to find that the world is on the brink of destruction and that he is humanity's last hope, forcing him to team up with a contemporary police officer to unravel a mystery that dates back to the founding fathers.
