This 2016 short film was presented by Crypt TV in 2017.

A man is alone in a cabin in the woods. He plays "Bloody Mary." The lights go out, and when they come back on, a very creepy boy and girl appear, warning him to hide, because "she's coming." So he hides. But of course that's futile... So, yeah, it's just a really creepy short film.
