Billionaire Oliver Queen returns from a five year stint marooned on a remote island with a mysterious agenda and recently acquired expertise as an archer. Determined to make up for his father's wrongdoings, Oliver assumes the identity of "Arrow", a vigilante archer dedicated to ending the corruption and crime that plagues the streets of Starling City.

In this update of Washington Irving's classic tale, Ichabod Crane (Tom Mison) wakes up in the 21st century but finds his 18th-century nemesis, the Headless Horseman, has also come along for the ride. After a local sheriff (Clancy Brown) is killed, Crane teams up with Det. Abbie Mills (Nicole Beharie) to sort out the mystery and its historical implications, though her supervisor, Capt. Frank Irving (Orlando Jones) is skeptical of all the supernatural shenanigans. And as Season 1 unfolds, these otherworldly events include encounters with menacing demons, frightening explorations of purgatory and impending visits by the Four Horsemen of the Apocalypse.
