A just paroled white supremacist and his ruthless girlfriend kill a cop and take an African American family hostage. Meanwhile, Sobecki, the heavily-tattooed supremacist leader who oversees his criminal empire from behind bars, is not thrilled when he learns of his charges screw-up. The patriarch of the family, an ornery ex-con himself, must rely on his wit and understanding of the racist mind to find a plan to free his family, but not before he confronts his own brand of bigotry and anger.
To make a movie about Aryans, you really need to have some sort of psychological insight into what makes them tick. Supremacy lacks any such insight, which makes it watchable, although never especially impactful.
