Out in the harsh, desolate Wyoming valley they call home, former construction worker Gideon and his wife Trish find themselves racing against the clock, caught in a bind as American as the beat-up F-250 pickup truck they hope holds on long enough to reach their destination.

The sun sets. The crows caw. The clock ticks.

If all goes to plan, they might make their deadline. Might save their family, their lives, their futures.

But out where the Wind River mountains loom, hardly anything man tries goes to plan.

A propulsive live-wire race that pits man against machine, against nature, and against the darkness that exists inside all of us.
