A small news team - reporter Sara, cameraman Milo and Charlie - is looking into the disappearance of a man named Dan. Going through the tapes he left behind, Milo spots the same thing again and again in the background: a tall, faceless figure in a suit. And now it seems to be watching them too. Based on the cult YouTube series Marble Hornets and the Slender Man legend, with Doug Jones as the Operator.
