Don't Kill It

As a man, Gabriel, and his dog are out hunting in southern Mississippi, the dog discovers and opens a small, unusual golden container while chasing a deer. When Gabriel relocates the dog, it acts strangely before violently attacking him. After shooting the dog, Gabriel returns home, displaying the same unusual behavior and black eyes. After killing his family, he enters a neighboring house and begins killing the family there before being shot dead by the family's father, Marcus, who immediately gets the same black eyes and proceeds to murder the rest of his family.
