Dr. Emory Charbonneau, a pediatrician and marathon runner, disappears on a mountain road in North Carolina. By the time her husband Jeff, miffed over a recent argument, reports her missing, the trail has grown cold. Literally. Fog and ice encapsulate the mountainous wilderness and paralyze the search for her. While police suspect Jeff of "instant divorce," Emory, suffering from an unexplained head injury, regains consciousness and finds herself the captive of a man whose violent past is so dark that he won't even tell her his name. She's determined to escape him, and willing to take any risks necessary to survive. As her husband's deception is revealed, and the FBI closes in on her captor, Emory begins to wonder if the man with no name is, in fact, her rescuer from those who wish her dead - and from heartbreak.
