A woman, her teenage daughter, a handsome laid-back, chauvinistic rancher - and the savagery of unseen forces at large in the mountain wilds of Utah. Lynn Nelson is beautiful, harried - and divorced. A thirty-five-year-old single mother, she agrees to help chaperon her teenage daughter Rory and nineteen other girls on a wilderness trip. It seems pretty simple at first, except that there's more lurking along these mountain trails than adolescent hormones.

Lynn Nelson, a Chicago anchorwoman, has planned a ten-day camping trip in Utah to bond with her teenage daughter, Rory. But their fall from a cliff is just the beginning of many nightmares they and their guide, the handsome Jess Feldman, must face.
