The story is a continuation of the previous one. After her husband sacrificed himself to protect his family, Evelyn (Emily Blunt) had to face new challenges of survival with her children (Millicent Simmons and Noah Jupe). They will be forced to leave their home and embark on an unknown journey. In the silent world, in addition to avoiding the hunting of the "sound-hunting monster", there are also new crises hidden at the end of the road covered with fine sand.
