Animals (1999)

The Evans' family vacation becomes a nightmare when a gang of cut-throats raid their trailer and camp site. Witnessing the murder of her mother Dana Miles-Evans and her step-father William Evans, Cassy Miles attempts to rescue her step-sister Ellen and avenge her family. The gang known just as ANIMALS have raped, tortured, and murdered in a crime spree that covers three states. Headed by their cold blooded leader MF the ANIMALS meet their match when Cassy seeks the help of Zeke Thompson, a former Navy Seal and friend of the family. Action up-stages horror, however, when the ANIMALS shoot it out with Zeke and Cassy in a climactic finale that turns the hunters into the hunted.
