Sleepy Hollow: Season 3

Nine months have passed since Katrina's death. A woman named Pandora encounters the Headless Horseman, seals him within a mysterious box, and summons a yaoguai, a demon that feeds on the fear of its victims. Ichabod reaches out to Abbie (who is now an FBI agent) after he is arrested and detained for smuggling an artifact into the United States. When Abbie arrives to collect him, he reveals Katrina's pendant, which is linked to the Horseman's power, has warned him of the latter's disappearance, m

A murder in a shopping mall is traced back to another demon, who targets those keeping dark secrets from others. To lure it in, Abbie reveals that she has recently found her absent father - although she has yet to tell Jenny - and Crane reveals General William Howe once offered him passage back to England in return for the names of rebel spies, which he nearly accepted.

Pandora gives a cursed knife to a troubled man, causing him to seek out and murder those he hates. Ichabod recalls a similar incident during his studies at Eton College in 1763, and identifies the knife as having once been used by Jack the Ripper. His research indicates that the knife itself has been linked to countless murders throughout history. As each wave of murders stopped amid a sudden outbreak of disease, the Witnesses realize that the curse can be broken by infecting the wielder. When a

Ichabod and Abbie investigate a case involving two sisters; the younger had fallen into a mysterious coma, and the other tells them that she witnessed her sister being attacked by a monster. They learn that the creature responsible is called the Abyzou, which Ichabod likens to the Tooth Fairy once they discover that the demon targets children who are about to lose, or have lost, a tooth and feeds on their soul. Ichabod remembers that Betsy Ross was in a similar situation with her niece, and had

Pandora reanimates General Howe and his soldiers as revenants, sending them to march on Sleepy Hollow during Halloween. Crane and Abbie break into Howe's grave, where they find mysterious bone fragments. Aided by Abbie's FBI contacts, Special Agent Seeley Booth (David Boreanaz) and Doctor Temperance "Bones" Brennan (Emily Deschanel), they trace the bones to an underground tomb beneath the Capitol, which was supposedly built for Washington and contains a prototype version of Greek fire, which Bre

Pandora summons an insect-like demon that drives its victims into a state of intense paranoia. Among them is Abbie's superior at the FBI, Reynolds, who tries to kill her in a rage before being subdued. Using notes from Betsy, Ichabod and Abbie destroy the creature in its lair, during which they discover Pandora's tree just as the sixth blossom is blooming.

Jenny realizes that she has actually absorbed the power of the Shard of Anubis while trying to keep it out of another hunter's hands. In retaliation, the hunter summons a trio of berserkers to search for her and drain her power. Although the creatures are Norse in origin, Crane realizes that they were summoned using Pandora's magic, protecting them from their traditional weakness, mistletoe. His plan to turn the berserkers against each other using Jenny's blood succeeds, but not before Jenny is

Ichabod identifies the deity summoned by Pandora as a Sumerian God known only as 'the Hidden One.' Having witnessed the Shard back when it was in Colonial hands, he realizes they need the casing it was in to draw it out of Jenny. Pandora reveals she is not Greek, but a Sumerian sorceress who has spent centuries gathering magic to revive the Hidden One, who she refers to as her "husband." While Ichabod and Joe distract them, Abbie starts draining the Shard's power into the casing. When the Hidden

One month later, Ichabod continues his frantic search for a way to find Abbie. While searching, he accidentally summons a demon that feeds on desperation and receives messages indicating Abbie is still alive. With the help of FBI agent Sophie Foster, Ichabod prevents the demon from killing Reynolds, who is grieving Abbie's disappearance, and traps it in an enchanted mirror where it is subsequently destroyed. Using a piece of her broken box, Pandora activates a beacon that draws all of the world'

While one month passes on Earth, ten months pass for Abbie as she explores the deserted and ruined world she is trapped in, the world Pandora took the Hidden One from. She has not needed to eat or sleep, and has not aged, but has found Betsy Ross's cutlass. By projecting his astral form into the mystical world, Ichabod reconnects with Abbie. Pandora appears and expels Ichabod's spirit, offering to free Abbie in return for the Shard. Abbie refuses and destroys it, using a portal inside a well mar

When the Kindred re-emerges and commits a series of murders, as well as abducting Ichabod's friend Zoe, he and Abbie learn that the creature has become resentful and seeks to make Zoe his bride. They locate the Kindress, a being created by Franklin to keep the Kindred calm, and bring her to life. The group rescues Zoe and watches as the Kindred and Kindress leave Sleepy Hollow forever. The Hidden One, who had earlier prompted the Kindred's rampage, uses his power to destroy both of them.

An old friend of August Corbin's, Atticus Nevins, returns to Sleepy Hollow and reaches out to Abbie with claims he's being tracked by a demon from his past. After being imprisoned, he explains that he and Corbin served in the army during the First Gulf War, during which their squad came across a ghoul guarding a cave full of gold. Corbin's notes reveal that the ghoul was summoned for the sole purpose of punishing grave robbers, and that it can be controlled with a golden scarab. Nevins reveals t

Ichabod and Abbie investigate a case involving the Jersey Devil, and learn that the person responsible was a man named Dr. Japeth Leeds, who used alchemy to mutate himself. When they uncover his lab, Abbie is drawn to the symbol, which is attached to a wax cylinder that they decide to play on the doctor's old phonograph. They watch a video recording that explains how the Hidden One was once the supreme ruler of humanity, until he was betrayed and cast down into the underworld to guard a box cont

During an FBI survival exercise in the woods, Abbie, Sophia and Reynolds race to save their guide who was attacked by a Dutch demon known as a Verslinder. While Reynolds goes to get help, Abbie and Sophie discover that the creature was imprisoned 400 years ago by settlers, having bonded itself to a man named Thomas. Meanwhile, Joe and Jenny encounter a fragment of the destroyed box at an auction and successfully bid for it. Pandora ambushes them as they try to leave and starts strangling Jenny,

Ichabod is confronted by The Hidden One at the archives and is saved by the symbol, which drains his magic and creates a mystic barrier around the Archives, trapping him and Ichabod within. In the tunnels, Abbie encounters Pandora and learns the symbol is known as the Emblem of Thura, and that it can contain even the strongest gods. With few other options, they agree to work together to destroy it. Meanwhile, Jenny, Joe, and Sophia investigate a case involving three men who were killed by a bans

The Hidden One reacts angrily to the news Pandora knew that Abbie and Ichabod had the emblem in their possession and strips her of most of her power. Pandora turns against him and visits the Witnesses, offering to help them recreate her box and imprison the Hidden One within it. Although skeptical, Ichabod listens on as she tells him it can only be regenerated in the catacombs where it was first forged. While searching for a golden thread left by Betsy Ross in the first American flag, they accid

Ichabod and Abbie travel to Pennsylvania and take a boat along the Delaware River, transporting themselves to the River Styx using the flag. Meanwhile Pandora, Reynolds, Jenny, and Joe along with Sophia travel to a remote mountain where the Hidden One plans to use the hourglass to regain his full power. To slow him down, they work to sabotage the ley lines surrounding the mountain. Along the way, Ichabod and Abbie discover the remains of an expedition led by Washington and Betsy to secure a port

In the antechamber of the temple, Ichabod restores the box, but soon realizes that the soul of a Witness is needed to use its power. Betsy is able to return to her own time while Abbie, who feels the effects of the box, joins Ichabod and Jenny in confronting the Hidden One. Ichabod returns the box to Pandora who uses it to absorb the Hidden One's power, but without a soul, the box is useless. Abbie sacrifices herself, while Ichabod and Jenny watch helplessly. As the Hidden One is now mortal, Jen
