During college, Scott (Kevin James) was an ambitious wrestler. His love for wrestling made his life full of challenges and passion. He naively thought that this passion would never fade. However, at the age of 42, Scott suddenly found himself a middle-aged teacher with a dull life, a dull working environment, no future and a stereotyped career. In his heart, a part of him had already died. In order to save money, the school decided to cancel the music class. As a music teacher, Marty (Henry Winkler) was about to be fired. Marty's tragic experience ignited Scott's fighting spirit, and he decided to help his friend. By playing underground boxing matches, Scott raised funds to keep his position in the music class in school, but his move was misunderstood by others. However, in Scott's heart, the answer to this question of giving up or sticking to it has long been clear.
