Jillian's idyllic vacation has become a living nightmare.
She graduated from St. Stephen's High School with honors, and after befriending three popular cheerleaders she tutored senior year, all four girls plan to spend an amazing week together at a secluded cabin on Crescent Lake.
But while jogging through the woods, Jillian takes a wrong turn and plunges down a ravine, injuring herself. Jeremiah Wolfe, a young local, finds her and carries her to his shack deep in the forest. His kindness and care gradually evolve into obsessive control as he refuses to go for help. He tells her that God brought her to be his wife, the helpmate he's been praying for.
What follows is a harrowing cat-and-mouse game as Jillian attempts to escape only to be thwarted by Jeremiah's uncanny ability to predict her every move. He won't allow anything—or anyone—to come between them. As the body count rises, Jillian realizes no one will be able to rescue her from this psychotic killer. She has to save herself, even if it means disobeying the 6th commandment: Thou shalt not murder.
