An Anthropologist's scientific Arctic expedition is hunted by the unknown. Coined by early explorers as the Atlantis of the North, the Arctic is a desolate, intense land colder than even Antarctica. Anthropologist Kate Foster accepts a job at an isolated research facility on a remote island surrounded by a vast ocean of crushing Pack Ice. Her scientific expedition becomes a mission of survival when she is joined by Detective Jack Decker with the Alaska Bureau of Investigations. Kate and Decker's team of criminologists race against time to solve the gruesome and multiple homicides of her colleagues while someone, or something (thought to be extinct), is hunting them.
