The detectives investigate the 2006 death of a teenage deaf boy. Blood confirming the identity of a teenage boy once believed to be missing is found at the city's one and only high school for the deaf. The detectives enter into what feels like a "foreign country" and try to determine who would want to kill Andy Rierden, a handsome, popular and straight-A student.
Before losing his hearing at the age of seven due to spinal meningitis, Andy had been a musical prodigy. His deaf parents believed he had adapted quite well to being deaf and was a proud member of the deaf community. But things were not as they seemed when it's discovered Andy had wanted a cochlear implant so he could hear again.
Andy's desire to hear the music he once played as a child drew hostility from the people around him including his deaf "girlfriend" who knew she didn't have a chance once he could hear, his principal who believed Andy belonged in the deaf world, and an overzealous father who didn't want his hearing daughter involved with a deaf boy. But the person who felt betrayed the most was his best friend Carlos. Left with a sense of abandonment that his best friend was leaving him for the hearing world Carlos was unable to contain his rage and jealously. Witnessing for the first time Andy's ability to hear the music again, Carlos unable to control himself kills his best friend.
