Hannah can't wait to sneak off for a romantic weekend with her boyfriend, Colin. He's leaving for college soon, and Hannah wants their trip to the lake house to be one they'll never forget.
But once Hannah and Colin get there, things start to seem a bit...off. They can't find the town on any map. The house they are staying in looks as if someone's been living there, even though it's been deserted for years. And Colin doesn't seem quite himself. As he grows more unstable, Hannah worries about Colin's dark side, and her own safety.
Nothing is as perfect as it seems, and what lies beneath may haunt her forever.
