I can’t remember the nationality of the film. Perhaps it was Spanish or Portuguese.
I know the story revolves around a family of witches (mother, boys, and girls). They need to perform a ritual sacrifice. Police are on their trail and this evolves into a Hard Boiled-esc firefight at the latter end of the movie (the only portion I’ve seen).
Not witches, but this could be the original We Are What We Are.
