Staunton Hill(2009)

When a group of hikers take off for a weekend of fun and adventure in remote mountain region, they unwittingly stumble across the Staunton family - for whom the hill is named - and find themselves at the mercy of a depraved, diabolical brood that will stop at nothing to rid their property of these "trespassers." The only law on Staunton's Hill is the law of the Stauntons...and, in this case, the penalty for defying that law is death.
