Kim Sang-nam (Jung Jae-young), a hot-tempered professional baseball player, is sent to the countryside to coach a team of hearing-impaired players in order to avoid media coverage of his recent involvement in an assault case. At first, Sang-nam has a difficult time imagining how he can teach baseball to a group of boys who can’t hear, but as he spends time with them he starts to believe that they can play the game. Motivated, Sang-nam decides to help them prepare for the nationals. As Sang-nam trains them, he forms bonds with the players, as well as with the music teacher and baseball manager Ms Na (Yoo Sun). But things don’t go the way Kim plans and their difficulties communicating with one another exacerbates the situation.
