Lim Deok-gyu (Hwang Jung-min), who once dreamed of becoming an Olympic boxing champion, is now almost defeated in his middle age. His noodle shop is deserted and his relationship with his daughter is very tense. At this juncture, he reluctantly participates in the "fighting reality show" with a generous bounty. If he doesn't make a name for himself, he will be amazing. Lim Deok-gyu defeats strong opponents one after another, and his confrontation with the gangster Shin Jae-seok (Yoon Je-moon) amazes the audience at the scene, on the computer, and in front of the TV. The ratings of the show have soared. Lim Deok-gyu not only has his own solid supporters, but also the business of the noodle shop has improved. Not long after, a good buddy from his youth, Lee Sang-hoon (Ryu Jun-sang), the director of a certain company who usually follows the boss's buttocks and nods and bows, comes to the other corner of the boxing ring. Living in each other's hearts is covered with thick dust. It's time to smash the hypocritical mask with your fists... This film is adapted from a popular Korean online comic.
