A killer with a screw loose sets his sights on Jacobia "Jake" Tiptree, whose latest renovation project becomes a dire matter of life and deck.

Driving to a cottage in the Maine woods with her best friend, Ellie White, Jake has a challenging week ahead of her. She bet her husband that she could finish building the cottage porch in only a few days - a lofty goal for even the craftiest home renovator. But as Jake and Ellie set to work, they soon realize that they're not alone. Dewey Hooper, a recently escaped convict, is watching them. Jake's testimony got him sent away for murder years ago and here, in the remote wilderness, he can exact his revenge. Tough as nails and not afraid to defend themselves, Jake and Ellie are determined to keep their wits about them - to prevent the quaint little cottage from turning into the ultimate death trap.
