When the grid dies at 10:12 on a Tuesday morning, Bo Henderson has one truck that still runs and 200 miles to cover. His son is trapped on a mountain tram. His grandfather waits at a bug out cabin at 8,000 feet with a secret buried under the ground.
Bo, his wife Theresa, their two kids, and their Akita must cross a collapsing New Mexico to reach it. But armed men found the mountain first, and someone Bo trusted has been mapping his family for years.
Not everyone makes it to spring.
