In 1781, during the American Revolutionary War, Captain Ichabod Crane (Tom Mison) under George Washington chopped off the head of a masked knight holding an axe on the battlefield, and he was seriously injured and lost consciousness. When he woke up again, he found that the world around him had changed drastically. At this time, he was in a modern American society 250 years later. At the same time, the sheriff of Sleepy Hollow was brutally murdered. His partner Abby Mills (Nicole Beharie) accidentally met Ichabod and learned that it was the gloomy headless knight who killed the sheriff. Ichabod learned what his wife Katrina (Katia Winter) did after he was injured, and realized from the records in the Bible that the evil four horsemen of the apocalypse were about to come to the world with the evil army from hell. After that, death and killing spread wantonly in Sleepy Hollow. Witches, blood curses, demons, and all kinds of ghosts and mysteries linger in American history from ancient times to the present, with far-reaching influence... This film is adapted from "The Legend of Sleepy Hollow" written by Washington Irving.
