The Substitute 3: Winner Takes All (1999)

Professional mercenary Karl Thomasson, his friend Macy, and an Albanian girl are being held in a brutal Kosovo prison where Macy is severely beaten. Just before he dies, Macy gives Karl a medal to give to Macy's daughter, Nicole Stewart, who is a professor of English at Eastern Atlantic University on Long Island in New York. Karl and the Albanian girl escape, and Karl kills their two captors. Three months later, Karl shows up at the university and visits Nicole, who is reluctant to accept Macy's medal because due to his military obligations, Macy was out of Nicole's life more than he was in it. Soon after Karl visits Nicole, she's brutally beaten up. When Karl hears of this, he has his friends Ed Lincoln and Rahmel help him take over as Nicole's substitute under a false name, then Karl brings another mercenary friend named Andy in on the investigation of the beating. Karl believes it was a member of the football team who did it, and then he discovers that members of the team have been doing anabolic steroids. Karl doesn't completely know what's going on until he and his mercenary friends investigate people such as head coach Bill Braden and Tony Lo Russo, the son of local crime boss Vincent "Vinnie The Brick" Lo Russo. That's when innocent lives are put in the most danger. Can Karl and his mercenary crew stop the forces behind the steroid plot?
