Ichabod Crane is resurrected and pulled two and a half centuries through time to unravel a mystery that dates all the way back to the founding fathers. Revived alongside Ichabod is the infamous Headless Horseman who is on a murderous rampage in present-day Sleepy Hollow. Bound to the Headless Horseman by a blood spell cast on the battlefield of the American Revolution, Ichabod quickly realizes that stopping Headless is just the beginning, as the resurrected rider is but the first of the Four Horsemen of the Apocalypse. As this re-invented Ichabod finds himself in present-day Sleepy Hollow, he discovers a town and a world he no longer recognizes. All that is brutally familiar are Headless and Ichabod's determination to annihilate this immortal being. It's a mission he must complete quickly, as Headless already has viciously slain Sheriff August Corbin.
Grey served both as mentor and father figure to Detective Abbie Mills, a young cop whose own supernatural experiences help her form an unlikely bond with Ichabod. But Sleepy Hollow's head of police, Captain Frank Irving, isn't buying any of this. In fact, the only person who is on Abbie's side is Ichabod. His extensive first-hand knowledge of our secret American history, coupled with her superior profiling and modern threat assessment skills, will make them a formidable duo as they work together to triumph over evil. The complex pasts of Ichabod and Abbie, from Ichabod's inclusion in the powerful and secretive Freemasons Society and the ghostly appearance of his late wife, Katrina, to Abbie's childhood visions, will help them solve the intricate puzzles of Sleepy Hollow in order to protect its future. As history repeats itself, the oddly-linked pair will draw on the real stories and hallowed secrets this nation was founded on in their quest to stop an increasingly vicious cycle of evil.
