The Substitute 3: Winner Takes All

Karl Thomasson (Treat Williams), a mercenary, comes to a college campus to look in on the daughter of an old war buddy. He finds Professor Nicole Stewart (Rebecca Staab) beaten, and the trail leads to the school's football players. Robert Radler sends him in undercover as a substitute teacher, a man trained for combat now standing in a classroom, determined to answer for what was done to her.
