IMDB.com
This is a pretty nasty piece of work that is nevertheless well made and effective. Race, rape and revenge but much more too when a modest God fearing black family are set upon by three escaped convicts who don't seem to like each other much more than do their captives. Much racist abuse and humiliation, though this all gets reversed as the family regain the upper hand and the 'by the book' cop makes an exception and allows the revenge to run it's course. Vile, exciting, hateful and touching by turns this is a very unusual, though non the more likable piece of exploitation cinema. Absolutely no way this film would be even considered today let alone be made and yet, in its own way it draws attention to that unspeakable prejudice within us all.
