Deaf teenager Zhang Cheng is preparing to transfer to a school for the deaf. The world of the deaf is no quieter than that of the hearing. When he discovered the "game" in the last row of the school bus, his joy of integrating into a new life turned into fear in an instant... Seeing his favorite girl Beibei covered in bruises in the game, his senior Xiaoguang's arrogant and unquestionable momentum, and a group of classmates who were innocent and harmless, Zhang Cheng wondered whether he should uncover the cruel truth of the game or join the ranks of the game? As the line between the perpetrator and the victim becomes increasingly blurred, the intricate pain, the unspeakable resentment, all kinds of confusion and anxiety spread in the silent campus. The first feature film by the emerging director Ke Zhennian boldly brought real events to the screen, facing the cruelty directly without losing his gentle eyes. The sharp portrayal of the complex and tangled emotions between the characters presents the cruelty that seems silent despite being hoarse. Beibei's words "They are just playing" are understated, but they are terrifying, painful, and a real lament.
