A highly contagious disease ravages the planet and secure within a desolate home, in an undisclosed location, with his vigilant, protective, and heavily armed parents (Joel Edgerton and Carmen Ejogo), 17-year-old Travis navigates fear, grief and paranoia amid scarce resources as a desperate young couple (Christopher Abbott and Riley Keough) seeks refuge in his family home with their young child.

After Sarah’s father, Bud, contracts the disease, they kill him, and burn his body in a shallow grave. Despite the best intentions of both families, panic, and mistrust boil over as the horrors of the outside world creep ever closer. But they are nothing compared to the horrors within, where Travis discovers that his father’s commitment to protecting the family may cost him more than he can afford to pay, including his own humanity. It Comes at Night is psychological horror thriller that is less interested in this contagion and its consequences than a more pressing threat to this family of three and the other threat, their fellow survivors, since there is no good place to wait out the end of the world.
