Following the deadly events at home, the Abbott family must now face the terrors of the outside world as they continue their fight for survival in silence. Forced to venture into the unknown, they quickly realize that the creatures that hunt by sound are not the only threats that lurk beyond the sand path. The film opens with a bracing sequence, a flashback to when the world fell apart, with the first terrifying glimpse of the invaders, the headlong scramble to find safety, and the realization that making noise was a very bad idea.
