Hearing-impaired teenager Chang Cheng transfers to a school for children with special needs. However, the world of the hearing-impaired doesn't seem quiet at all. When Chang witnesses the "game" taking place in the last row on the school bus, his excitement about blending into a new environment immediately turns into fear. Seeing Bei Bei, the girl he has a crush on, getting hurt so badly, Xiao Guang, the ringleader, behaving like a king and other schoolmates acting innocent, Chang debates with himself on whether he should reveal the cruel truth about the game or whether he should join in.
