North Carolina, 1949. When agricultural inspector Charlie Danwitter is sent on a special assignment to bucolic Ashe County, he expects an easy job cataloging heirloom apple varieties. However, when the local farmers grow suspicious of his motives, Charlie finds himself in far more trouble than he bargained for. In an attempt to salvage his assignment, he follows a mysterious woman deep into the beating heart of the Blue Ridge Mountains to a long-forgotten village where harvest rituals are rooted in bizarre Old World customs—and discovers that some traditions are better left in the past.
