The Lotte Giants’ Choi Dong-won (Cho Seung-woo) and the Haitai Tigers’ Sun Dong-yeol (Yang Dong-geun) are rival pitchers in 1980s baseball. The film reenacts the legendary match of May 16, 1987, which baseball fans today still recall as “the perfect match,” when Choi and Sun compete as pitchers for the last time.
