For a communications class project, the students are assigned to make a video about someone they consider a hero. Eric tries to impress Heather the cheerleader but she' not interested because he's a benchwarmer on the football team. Katie is excited that her old boyfriend will be in town next week, but Nicky is worried about it. At the game that weekend, Mr. Belding accidentally injures himself, a player and a cheerleader on the sidelines. From the locker room Screech watches as Eric is put in the game and scores a last-minute game-winning touchdown. At school Eric is now a hero, and Heather is suddenly interested in him. Maria and Rachel ask Eric to be the subject of their documentary. He agrees, but he blows them off to go out with Heather. Ryan begins to sell T-shirts autographed by Eric. With tryouts for a new cheerleader, Katie is too busy to spend time with Nicky.

The annual Bayside Science Fair is coming up and Screech desperately wants to win. Eric may be the school's only hope for winning with his robot duster invention, but Screech insists on enhancing his creation which could get Eric disqualified from the competition.
