Blood Clan (1990)

In the past, a family is executed by soldiers for cannibalism - except for the little girl, Katy Bane McKay. She is adopted by Judge Mackay and goes home with him to Canada, where she grows up with no knowledge of her family's pass. Then, in the present, several deaths occur and people begin to think it's Katy Bane McKay. After all -- blood will out.
