Plot synopsis:
Former Division I collegiate wrestler Scott Voss is a 42-year-old bored and disillusioned biology teacher at the failing Wilkinson High School. Budget cutbacks at the school jeopardize the continuation of its music program, which would result in its teacher, Marty, being laid off. Concerned for both his colleague and his students, Scott attempts to raise the $48,000 necessary to keep the music program alive. He moonlights as a night instructor for an adult citizenship class, where student Niko asks him for outside tutoring. When Scott arrives at Niko's apartment, he learns that Niko was a former mixed martial arts (MMA) fighter. While watching the UFC at Niko's apartment, Scott learns that the loser of a fight receives $10,000, which gives him the idea of raising the money by fighting and losing in MMA. Scott, helped by Niko and Marty, begins with small unsanctioned bouts paying only $750 to the loser. Niko begins training him in defense, later adding trainer Mark to teach offense, after Scott knocks out an opponent and realizes that wins give larger payouts, needing fewer fights to achieve his $48,000 goal. While Mark trains with Scott, Malia De La Cruz, one of Scott's students and a band member, helps Niko study for his citizenship test by putting the information into songs. Scott then begins fighting in small MMA fights and gradually gaining higher amounts of money for the school.
Scott has been pursuing the school nurse, Bella, and they share moments revealing affection for each other, while also rekindling Scott's passion for teaching. Scott is within $6,000 of his goal, when Mark tells him that Niko turned down a sanctioned UFC fight offered by Joe Rogan, with the certainty of earning $10,000 for a loss. Scott angrily confronts Niko, who apologizes and admits he turned it down because he was jealous – Niko was once asked to fight at the UFC but suffered a neck injury while training for it, ending his career. Scott and Niko accept the offer, with Scott and his crew soon travelling to the MGM Grand Las Vegas for the fight. Once he arrives, he learns that school administrator Elkins has been embezzling from the winnings and the school, meaning all Scott's efforts have been in vain. Scott decides he must win the fight and the $50,000 purse.
The publicity of Scott's slow rise to fame has grown, and the school's band appears in the stands to play his theme song, thanks to Bella contacting Rogan. Marty reminds Scott that even if he does not win, he has inspired the students, which is their real purpose. Scott has no answer to his dangerous opponent, Ken Dietrich, who is angered that his original opponent canceled and that he is stuck with a man that "does not deserve" to be at the UFC. After finding inspiration from the students, Scott manages to win the fight, earning $50,000 and Dietrich's respect. Scott and Bella kiss through the chain link fence of the octagon.
A subplot involves student Malia, her father, and Scott's brother Eric, who is unhappily self-employed as a house painter. Eric has a large family and both he and his wife have low paying jobs; Eric enjoys cooking. Malia's father has a restaurant that is failing since his chef quit. Malia's father wants her to stop music and focus less on school so that she can help with the restaurant, but she has a passion for music. Scott encourages Malia to pursue her musical talent, which drives hostility from her father to Scott for "causing his daughter to disobey him". Eric becomes the chef for her father's restaurant, which improves the business, so Malia's father is thankful to Scott. Once Malia sings Scott's theme song at the UFC fight, shown on TV, her father accepts that music is her true passion.
In the closing scene, Niko and all of the students in Scott's citizenship class attend their American citizenship ceremony.
