Based on the true account of what took place at a school for the hearing impaired in South Korea. In 2000, a principal and some faculty members had begun to sexually molest and abuse several hearing impaired students at their school for close to 4 consecutive years. Though we may not want to accept it, it is time to face this horrible inhumane truth.

Kang In-ho (Gong Yoo) is the newly appointed art teacher at Benevolence Academy, a school for hearing-impaired children in the fictional city of Mujin, North Jeolla Province. He has a dark past - his wife committed suicide a year ago, and his sick daughter is under the care of his mother. He is excited to teach his new students, yet the children are aloof and distant, trying to avoid running into him as much as possible. In-ho does not give up, however, trying to show the kids that he cares. When the children finally open up, In-ho faces the shocking and ugly truth about the school and what the students have been enduring in secret: the children are being physically and sexually abused by their teachers. When he decides to fight for the children's rights and expose the crimes being committed at the school, In-ho teams up with human rights activist Seo Yoo-jin (Jung Yu-mi). But he and Yoo-jin soon realize the school's principal and teachers, and even the police, prosecutors and churches in the community are actually trying to cover up the truth. In addition to using "privileges of former post" (Jeon-gwan ye-u) the accused do not hesitate to lie and bribe their way to get very light sentences.
