|Ho-chang is a late Joseon Dynasty scholar who likes sports more than studying. However, he loses his only dream when the state civil service examination is abolished and lives in despair. His brother leaves home to become a member of the loyal troops in the cause of justice out of animosity towards the society. Ho-chang's father is forced out of his government post by the reformist party and runs a private school. One day, Ho-chang sees that a Westernized Korean woman, Jeong-rim, playing baseball with some missionaries at the YMCA hall. He becomes interested in baseball and Jeong-rim. Ho-chang's father urges him to inherit the private village school but Ho-chang only grows his love towards Jeong-rim and the game of new civilization: baseball. He and his best friend Gwang-tae, Dae-hyeon who studied in Japan, and Jeong-rim form Joseon's first baseball team. The "YMCA Baseball Team" becomes the top baseball team, never losing a game and is loved by the Hwang-seong citizens. Meanwhile, Joseon is forced to sign the Eulsa Protectorate Treaty with Japan. Being totally indignant upon hearing the news, Jeong-rim's father kills himself. After the Eulsa treaty, the YMCA baseball team's practice field becomes Japanese soldier's post. The offended YMCA baseball team players have the first match against Japan's club team, the Seongnam Club. However, the day before the game, Dae-hyeon, the pitcher, attempts to terrorize the pro-Japanese party and is instead injured. He does a horrible job after all. Ho-chang, as well, cannot display his full potential because he is trying to avoid the eyes of his father on the stadium. His father has found his son's baseball uniform washed and hung on the wash line. The YMCA baseball team is defeated by the Japanese team. Dae-hyeon, the team's captain, asks Japan's captain, Gachunori for a rematch. However, now that the Japan team gets the whole picture as to who was behind the previous night's terror attack, Dae-hyeon and Jeong-rim are chased by the Japanese army. The YMCA baseball team breaks up. Disappointed, Ho-chang follows his father back to their hometown and helps with the private school work.
