When attorney Elizabeth English and her husband, Paul, catch up to their energetic sons at the end of their hike, they expect to find the two boys waiting by their car.

But when Elizabeth and Paul emerge from the trail, Henry is gone, and all Nick says is that he saw a lone truck leaving the lot shortly after Henry went to the bathroom. Gritty park ranger Hollis Monroe launches a massive search and teams up with a local detective to investigate the possibility that Henry was kidnapped.
