In a post-apocalyptic world, a family is forced to live in silence while hiding from monsters with ultra-sensitive hearing.
In a devastated Earth overrun by invincible predators of a possible extraterrestrial origin, the Abbotts find themselves struggling to survive in the isolation of upstate New York, defined by a new era of utter silence. Indeed, as this new type of invader is attracted to noise, even the slightest of sounds can be deadly; however, its been already twelve months since the powerful monsters first sightings, and this resilient family still stands strong. Of course, learning the rules of survival in this muted dystopia is essential; nevertheless, now, of all times, an otherwise joyous event puts in jeopardy the already fragile stability. And now, more than ever, the Abbotts must not make a sound.
The story of the young Abbott family is told starting on day eighty-nine of their ordeal. Unaware if anyone else on Earth is still alive besides them, they have to remain as silent as possible under most circumstances, which means no speaking, to evade deadly and seemingly indestructible armored creatures which track their targets solely by sound and which have led to the Abbotts solitary existence. This existence is made all the more difficult for eldest offspring Regan in being deaf and thus unable to gauge the issue of sound, which is why father, Lee, is constantly trying to devise ways to upgrade her cochlear implant if only for her survival. Under these circumstances, the family tries as best it can to lead as normal a life as possible with devised safeguards to protect them despite anything that may happen to them potentially to throw them off this routine of mock normalcy and survival. Through this ordeal, they also try to learn as much as they can about the creatures in the hope of someday being able to destroy them to regain their lives. For parents Lee and Evelyn, the first priority is protecting the children at all cost, which the children may not always see or understand especially concerning the day eighty-nine incident.
