Gang In-ho needs to earn money in order for his daughter to have surgery. He is sent to work for a school for deaf children, but what he finds there is beyond comprehension. The children are being abused by the staff members, both physically and sexually. He is so appalled by the situation that he attempts to expose the truth about the school. He enlists the help of a human rights activist to bring the treachery to an end. What they did not expect was that the school faculty and staff, local churches and law enforcement officials will do anything to keep the dirty little secrets that are held within the walls of the school.
