In the vast wilderness of the Appalachian Trail, three hikers are searching for answers. Taz Chavis, just released from prison, sees the thru-hike as his path to salvation and a way to distance himself from a toxic relationship. Simone Decker, a young scientist with a dark secret, is desperate to quell her demons. Richard Nelson, a Blackfoot Indian, seeks a final adventure before taking over the family business back home. As they battle hunger, thirst, and loneliness, and traverse the rugged terrain, their paths begin to intersect, and it soon becomes clear that surviving the elements may be the least of their concerns. Hikers are dying along the trail, their broken bodies splayed on the rocks below. Are these falls accidental, the result of carelessness, or is something more sinister at work?
