A new football team in the K-league, Incheon United FC, is founded and Jang Oi-ryong joins the team as the head coach. One by one he accomplishes the goals he suggested, building up trust with the team. However, circumstances surrounding the team are still poor. Without enough rest between games, the players are getting tired and injured. Im Jung-yong, captain of the team, continues playing even with a serious eye injury. He finally goes to the hospital and receives the diagnosis that he is losing his eyesight because he neglected his eyestrain for too long. To preserve the team’s morale and to hide their weak point from opponents, his condition is sealed as a secret until the last game of the season.
