In a post-apocalyptic world where mysterious blind creatures stalk the survivors, the Abbott family has adapted to a life of absolute silence. With extraordinarily keen hearing, these monsters attack any human that makes the slightest noise. To protect themselves, the Abbotts have developed a lifestyle that includes the use of sign language and the construction of a nearly soundless home.
The leader of the family, Lee, and his wife, Evelyn, are desperate to keep their three children safe: Regan, the oldest daughter, who bears the guilt of a family accident; Marcus, the sensitive and fearful son; and their little boy, who represents the purest vulnerability in this terrifying landscape. As the story unfolds, the tension is palpable with every step they take, every crack of a twig, or the whisper of the wind. Their efforts to live in silence are threatened when Evelyn discovers she is expecting another baby, which adds even more danger to their already fragile existence.
Having to prepare for the arrival of a new member in the midst of a hostile world is an almost impossible challenge. As the family struggles to find ways to communicate and survive, a series of events unfolds that will test their strength and family bonds. The film is a blend of anguish, love, and sacrifice, in an environment where the slightest sound could mean death.
