In Alaska, nature can be cruel... but human nature is crueler. After an early spring thaw on the Alaskan coast, Anchorage police discover a gruesome new piece of evidence in their search for a serial killer – a dismembered human foot. In the remote northern town of Deadhorse, Deputy US Marshal Arliss Cutter escorts four very dangerous handcuffed prisoners onto a small bush plane. He’s expecting a routine mission and a nonstop flight... But everything goes wrong. When the plane goes down in the wilderness, all hell breaks loose. The prisoners murder the pilot and a guard and torch the plane. But the nightmare is only just beginning. Back in Anchorage, deputy Lola Teariki has traced the dismembered foot to a missing girl--and the serial psychopath who slaughtered her. It's one of the prisoners on Cutter's flight... Now it's a deadly game of survival. With no means of communication, few supplies, and ravenous grizzly bears and wolves lurking in the shadows, Cutter has to battle the unforgiving elements while the killer wants his head on a stick.
