In 18th century New York, there was a police officer named Ichabod Crane (played by Johnny Depp) who put forward a revolutionary idea - using science to help the police investigate crimes. Since his methods posed a great potential threat to the established police system, he was sent to a remote northern town called "SLEEPY HOLLOW" (Sleepy Hollow) to investigate a series of murders. In the sinister and dangerous black forest on the outskirts of the town, several headless corpses were found. Many locals believed that they were the work of a ghostly midnight rider without a head, wielding an axe, riding a black horse. The residents of the town all thought this headless knight was an evil devil. Although Crane was a little afraid, as someone who is intelligent and firmly believes in science, he could not accept this rumor.
