A survival horror tale built around the Slender Man legend, Slender: The Arrival follows a young woman named Lauren who travels to the secluded Oakside Park to help her childhood best friend Kate move out of her family home. When she arrives, she finds the house empty and unsettled, Kate's belongings scattered and her bedroom covered in frantic drawings and scrawled warnings about a tall, faceless figure. With Kate nowhere to be found and screams echoing from beyond the tree line, Lauren steps out into the surrounding forest to search for her friend. Armed with nothing but a flashlight, she picks her way through the darkened woods and abandoned places, gathering scattered clues to Kate's fate. But she is not alone in the dark. The Slender Man stalks the shadows, an entity that appears and vanishes without warning, and Lauren soon realizes that uncovering the truth of Kate's disappearance means surviving whatever is hunting her among the trees.
