With his father in a nursing home and his mother needing support, former Great Smoky Mountains park ranger Lincoln Vailes moves to the bayou town of Eternal Springs, Louisiana, to become a police officer. Recent college graduate and eager social worker Jade Laurent has also moved there to try and right the wrongs of an abusive past. But someone is running her car off the road and pointing guns in her direction. As Lincoln investigates her case, he uncovers ties to big-city gang warfare up north that appears to be making its evil way down south.
