Dog (2009)

"A vast salvage yard, lies nestled in the woods, on the edge of a Mid-Western town. Owned and operated by a pair of sadistic, murderous brothers, the yard is a place of death and unimaginable horror. At night, the salvage yard is watched over, not by canines of the four-legged breed, but by "Dog", the owners' tormented younger brother. Warped by years of abuse at the hands of his brothers, horribly deformed by generations of in-breeding, the feral boy (more beast, than man) prowls the shadowy confines of the junk yard, slaughtering anyone foolish enough to enter after night falls." There's more, of course...much more!
