Hiding from her abusive, estranged husband, Cameron Cramewell lives in a rural house with her 9-year-old twins, Daniel and Zane. Young Daniel receives nightly visits from ghoulish kids who show him disturbing images of families being slaughtered. It's all part of the grand plan of Slender Man, the evil spirit who recruits innocent children to murder their loved ones. The only hope for his intended new victims may be a former deputy who's familiar with SlenderMan's fiendish work from the past.
