Do Not Unto Others is the convoluted story of the devil, his dark dog, the doctor marked by a family secret, and the unsuspecting teacher who walks into the middle of a nightmare of vengeance for a terrible mistake made years ago. In the beginning, the grisly deaths in the small southern town of Sinclair appear to be random, but finally the deadly puzzle pieces fall into place. Some townspeople will live, and others will die; but all are terrified by the beast that walks through the darkness.
