Paul et Jennifer Hemdale viennent d'entrer dans la maison de leurs rêves. Mais leur mariage heureux est sur le point d'être mis à l'épreuve car ils découvrent lentement le secret derrière la chambre noire dans la cave. Une autre chose vit déjà dans leur nouvelle maison et elle se renforce tous les jours.

In a post-apocalyptic world, two young women cling to life in an abandoned resort. They must survive in silence, in mortal fear of attracting the hordes of undead that roam the Earth. When their compound runs out of fuel, they are forced into the countryside to find gas, resulting in a nightmarish encounter with survivors. However, that is nothing compared to the horrors that await them back at home, leading to a deadly confrontation with the evil that surrounds them.
