Former collegiate wrestler Scott Voss (Kevin James) is a 42-year-old, apathetic high school teacher. When budget cutbacks threaten to cancel some of the school’s programs and lay off its music teacher (Henry Winkler), Scott creates a scheme to raise money by moonlighting as a mixed martial arts fighter. Everyone thinks Scott is crazy – most of all the school nurse, Bella (Salma Hayek). In his quest, Scott gains something he never expected as he inspires his students and becomes a sensation that rallies the entire school.
