Nathan Townsend is hiking the Appalachian Trail.
Unlike the other through-hikers who attempt to walk the entire 2,100-mile long footpath, however, Nate isn't traveling for adventure or challenge - he's walking to escape.

With each mile on the trail, he steps further and further away from the people and events that have irreparably scarred him. As he crosses paths with a barrage of fellow hikers and
townspeople, each carrying their own wounds, he must revisit step-by-step the events that put him on the long trail from Maine to Georgia.

Eventually, Nate must make a choice between walking away and reaching out, including to the one woman desperate to rescue him and help him find his trail's end.
