When natural disaster forces Walker and Nataya to re-evaluate their future, an opportunity to visit friends in Washington State offers a respite from the daily reminders of their tragic loss. But shortly after arriving they're asked to help find a family missing in the local wilderness. Despite their limited experience in that specific environment, the two survival experts don't hesitate to join the search.
However, what should've been an easy rescue meets with an unexpected complication, and a bad scenario soon turns to worse when an early snowstorm strands Walker and his charges—a father and eight-year-old son—in the mountains without proper gear or provisions.
Constantly challenged by the unfamiliar terrain, Walker is forced to repeatedly find alternative ways to deal with an environment far different from where his skills were honed. And after he becomes impaired by serious injuries that cause him to mistrust his own judgment, what was once a worse scenario quickly becomes a worst-case scenario for all three of them.
It's nature versus man, and man versus his own nature, as Walker fights for his charges' survival... as well as his own.
