Following a 250-year slumber, Ichabod Crane (Tom Mison) devotes his life and knowledge of the supernatural to defeating the demonic that plague present-day Sleepy Hollow. But after the climactic events of Season Three - and the death of his partner and fellow Witness, Abbie Mills- Crane's world is turned upside down. He is then led out of town by a mysterious group promising to put him in charge of an evil-fighting organization created hundreds of years ago by none other than George Washington. Crane now finds himself in an all-new city working with all-new allies as he embarks on his most important mission yet: save Washington, D.D. from otherworldly threats that promise harm, not only to the United States and its people, but to the soul of democracy itself.
