Tate McGillis escapes to a secluded mountain cabin with his girlfriend, Lauren, for a weekend away. His romantic plans are destroyed, however, when he encounters an evil the likes of which he never imagined.

It's not Lauren's husband; he had no idea she left. It's not the dark, sinister forest that is constantly changing around them. It's not the undead crawling out of the lake with a taste for human flesh. It's not even the mutated spirit of a serial killer tormenting Tate for its own demonic pleasure.

A woman who will only identify herself as Mary Sue Standin is stalking Tate , and her powers are unrivaled. She can break his bones with a thought. She can rip everyone and everything he loves from the very fabric of reality. She can teleport him at will, leaving Tate to question the very nature of his existence.

Because Mary Sue is the writer of his story, and Tate's is not a happy story.
