baby doesn't react to fire truck siren

A family is forced to live in silence while hiding from creatures that hunt by sound.

A farm in Romania, far from any city. A young woman, Cristina, returns to her family after years away. Her parents treat her like a leper. Cristina only feels some kind of affection and familiarity for her younger sister, Marina. Where Cristina has been and how she has managed to survive remain unspoken – as indeed everything remains unspoken in the idyll of this apparently, at first glance, very tranquil place...

Following the events at home, the Abbott family now face the terrors of the outside world. Forced to venture into the unknown, they realize that the creatures that hunt by sound are not the only threats that lurk beyond the sand path.

The third instalment in the franchise. Plot TBA.
