Kate Cypher returns to the town of her childhood to look after her elderly mother, but faces unexpected hostility from the locals. It turns out that a girl was recently murdered in the area, and her death is suspiciously similar to an accident that happened many years ago to Del Griswold, Kate's classmate. This story gave rise to the urban legend of the mysterious Potato Girl who wanders the woods alone. Kate, of course, doesn't believe in ghosts, but when Nick, Del's older brother, comes to her and asks her to contact her dead sister, Kate's sanity is seriously tested.
