How far would you go to keep a secret? Nathan has never been able to forget the worst night of his life: a party that led to the sudden, shocking death of a young woman. Only he and Bob, an old acquaintance, know what really happened and they have resolved to keep it that way. But one rainy night, years later, Bob appears at Nathan's door with terrifying news; the woods are being dug up.
