There are a symphony of almost undetectable sounds that make up a moment of silence, and Peter Lucian (Peter Sarsgaard) is determined to catalogue them all. Through his job as a New York City "house tuner," the hyper-methodical Peter works meticulously to diagnose the discordant ambient noises-produced by everything from wind patterns to humming electrical appliances-adversely affecting his clients' moods. When he takes on the particularly difficult case of Ellen (Rashida Jones), a lonely woman plagued by chronic exhaustion, Peter finds that the mysteries of the soul may be even greater than the mysteries of sound. A quietly moving portrait of a harmony-obsessed man learning to embrace the dissonances of human emotion, The Sound of Silence invites viewers to hear the world with fresh ears.
