For the uninitiated, Slender Man (also known as Slenderman) is a fictitious character/creepypasta meme of an abnormally tall, faceless man with long arms who stalks and abducts children.
In a small town in Massachusetts, four high school girls perform a ritual in an attempt to debunk the lore of Slender Man.
Screen Gems has released the trailer for their upcoming horror film, Slender Man, based on the internet phenomenon that has a self-explanatory name but a terrifying visage.
