What could be more restful, more restorative, than a weekend getaway with family and friends? An isolated luxury cabin in the woods, complete with spectacular views, a hot tub and a personal chef. Hannah's loving and generous tech-mogul brother found the listing online. The reviews are stellar. It's his birthday gift to Hannah and includes their spouses and another couple. The six friends need this trip with good food, good company and lots of R & R, far from the chatter and pressures of modern life. But the dreamy weekend is about to turn into a nightmare.
