There's a poisonous secret behind these bucolic scenes …

When a powerful development company sets its sights on Mason County, Virginia, as the location for a sprawling resort for the rich, the locals begin taking sides. Many residents see the resort as economic salvation for the small Blue Ridge Mountains community, while others fear the county will become financially dependent on a predatory company.

Few oppose the development more vocally than veterinarian Rachel Goddard. She sides with locals reluctant to sell their land and, in the process, complicates the life of her new husband, Sheriff Tom Bridger.

When a beloved couple is gunned down on the very farm they refused to sell, it seems supporters will stop at nothing to ensure the success of the resort. Now, disagreement in the community has exploded into civil war, with both sides lashing out. As the violence escalates, Rachel discovers the attacks are more sinister than they appear.

Can she bring the truth to light before her community tears itself apart?
