Butcher House (2006)

Sinopsis: In the 1960's at Arthur Kingston's old butcher house blood and guts were routine. That all changed one night when the blood spilled was human. At the hand of a murderous, rampaging butcher, two workers and the owner's son were killed. The factory was shut down. Decades pass. The massacre became a legend, but the abandoned butcher house still held the evil in its halls. As six teenagers explore the old butcher house, they unleash the horror that lies within.
