A family with two children lives on a remote farm. It would seem that the lives of these people are not at all different from the lives of other such families, but they live in a place that is filled with horrible monsters reacting to any sound. The family has learned a whole complex of special gestures that help them communicate with each other without issuing a single sound. In addition, each family member must move very quietly so that dangerous creatures do not hear them. However, the house where children live can not be the quietest place on earth.
