The Substitute 4: Failure Is Not an Option

An undercover commando poses as a teacher to root out the neo-Nazis at a military academy in this fourth installment of the tough-love educational/action saga. At the behest of a friend, commando Karl Thomasson (Treat Williams) heads to an Atlanta academy so he can root out the racist skinheads who are running amok. As it turns out, the little white supremacists are working at the behest of the school's uber-racist headmaster, Brack (Patrick Kilpatrick). Thomasson finds an ally, or at least a bedmate, in the person of Jenny (Angie Everhart), the school's medical officer. Meanwhile, he bullies the skinheads, rallies the other students, and uncovers a plot to blow up a minority-built nuclear power plant. Although this is the fourth episode in the series, it's only the third outing for Williams, who took over from Tom Berenger in the second installment. Director Bob Radler previously helmed The Substitute 3: Winner Takes All. ~ Brian J. Dillard, All Movie Guide
