In the town of Sleepy Hollow in 1781, Ichabod Crane (Tom Mison) decapitates the Headless Horseman in battle, but is mortally wounded himself, and collapses. Both he and the Horseman awaken in 2013 in the same town. The latter kills the local sheriff, August Corbin (Clancy Brown), and Crane is mistakenly arrested for his murder by Corbin's partner, Lieutenant Abbie Mills (Nicole Beharie). Crane claims that he's innocent of the murder and has just risen after several centuries of entombment. Mills
Mills' superior Frank Irving (Orlando Jones) reluctantly allows her to work with Crane due to the events occurring in Sleepy Hollow; the two begin using Corbin's gathered archives of occult material. Elsewhere, Andy Brooks (John Cho), a former fellow deputy who was killed in the previous episode assisting the Horseman, is reanimated and given new orders to resurrect the witch Serilda of Abaddon (Monique Ganderton). Serilda completes the ritual for her resurrection by hunting down and killing the
A psychoanalyst connected to the Mills sisters mysteriously commits suicide and Crane and Abbie Mills visit Jenny at the institution. When others commit suicide as well, the Witnesses learn that the source of the mysterious deaths is the Mohawk dream spirit Ro'kenhronteys, or the Sandman. By entering the dream world of this spirit, they are able to resolve the problem and confront their past guilts and atone for them. When Mills goes to re-visit her sister, she learns that Jenny has escaped.
Mills and Crane search for Jenny, tracking her down to a cabin belonging to Corbin. Mills further learns that Corbin had Jenny track down rare and often magical objects, such as a sextant. This object reveals an old map of Sleepy Hollow marking the hidden location of The Lesser Key of Solomon, a book that can open a doorway to the seventh circle of Hell. A secret society of Hessians aligned with the Horseman get their hands on both the sextant and the book, but Mills destroys the book and ends t
A sickly boy suffering from an unknown disease is discovered in the woods and immediately put under CDC quarantine. Because the boy can only speak Middle English and says he is from Roanoke, Crane deduces that the child is from the lost Roanoke Colony. Investigating, the Witnesses discover that the colony was transported to an alternate dimension and the people within are suffering from - but not dying from - the same illness, originating from the second Horseman, Pestilence. The boy was lured o
Crane is kidnapped by Freemasons and, after confirming his identity, they ask him to take poison that will kill him as well as the Horseman (since their blood is linked occultly). Mills tracks down a sin eater named Henry Parrish (John Noble) so that Crane can be purged of his sins, and together they prepare for the Horseman's return that evening at nightfall.
Crane discovers the Freemasons in Sleepy Hollow have been beheaded by the Horseman, and realizes that the creature is seeking its own head. Irving recovers the head from the lab (where it has stymied attempts to categorize it) before the Horseman comes for it, barely escaping with his life. Crane and Mills cannot destroy the head by normal means, so they use it to lure and trap the Horseman within a magical chamber built by Thomas Jefferson.
Mills and Crane interrogate the Horseman with Andy's help, despite the dead policeman's warnings not to do so. During the interrogation, the Horseman reveals himself to be Abraham Van Brunt, Katrina's former fiancé and Ichabod's friend who was killed by Hessians and turned into the Horseman by Moloch. Brooks, under Moloch's control, sneaks a druidic relic into the chamber where the Horseman is being held and uses it to free him. This allows Moloch's hellish minions to be summoned into the chambe
Mills and Crane investigate the missing persons case of Lena Gilbert (Erin Cahill), the wealthy granddaughter of a mining and oil magnate. Lena went missing while visiting her family's country home, which was once owned by Lachlan, a friend of Ichabod's, who put a hex around the house as a protective spell. Crane takes an interest in the case because Lena circled a name, "Katrina C" (which he assumes is Katrina Crane) in a paper that she left behind. Lena explains that Katrina was the last perso
Ichabod and Abbie enlist the help of Henry Parrish to find information about Ichabod's son. Henry sends Ichabod to purgatory to confront Katrina's soul, learning that the boy's name is Jeremy. When Ichabod returns, he, Abbie, and Henry search to find the golem that was summoned by Jeremy centuries ago, and now seeks revenge on the coven that disowned his mother. After destroying the golem, the Witnesses receive a threatening message from Moloch.
Ancitif, a minion of Moloch with the ability to jump from body to body and possess its victims via physical contact, returns to Sleepy Hollow after a seven year absence and delivers a foreboding warning to Captain Irving: unless he delivers George Washington’s Bible – a valuable resource in the war against Moloch - great harm will befall his disabled daughter, Macey.
Ichabod and Abbie, while studying George Washington's Bible, learn of a map of purgatory that was created after Washington's death and was likely buried along with his body in a secret location. They enlist the help of Henry Parrish in locating Washington's burial site. Meanwhile, Andy, after failing to persuade Abbie to give him the map, is granted demonic powers by Moloch. Inside Washington's tomb, Ichabod, Abbie, and Henry locate the map, but are then ambushed by Andy. Only Ichabod's quick th
Ichabod and Abbie travel to purgatory to enlist the help of Katrina when they learn from Henry Parrish that the third horseman, War, will appear in the real world during a forthcoming eclipse. When they arrive, Abbie and Ichabod are separated and placed in illusionary worlds where they are not Witnesses. When they both come to realize that what they are seeing is not real, they reunite and travel to an old church to find Katrina. There, Abbie and Ichabod learn from Katrina that she is unable to
