In the premiere trailer for the horror feature The Bye Bye Man, we are taken through a slideshow of images depicting the supernatural entity that is The Bye Bye Man. "He's real," a terrified college student named Elliot warns, as Detective Shaw (Carrie-Anne Moss) interrogates him about a gruesome on-campus crime. As she attempts to get more information, the traumatized young man tearfully pleads, "Please don't make me say it." What Shaw doesn't know is that Elliot and his friends have unwittingly found themselves the targets of this mythical demon, who is known to possess a person's body and force them into ungodly acts of terror and bloodshed.
