It Comes at Night

A highly contagious outbreak has ravaged the world. Paul, his wife Sarah, and their teenage son Travis have secluded themselves in their home deep in the woods in an undisclosed location. When Sarah's father, Bud, contracts the disease, they kill him and bury his body in a shallow grave. The next night, they capture an intruder breaking into the house. Paul ties him to a tree and places a bag over his head overnight to confirm he is not suffering from the disease. The stranger, Will, explains that he did not know the house was occupied and was only searching for fresh water for himself, his wife, and his young son. Will offers to trade some of their supply of food for water. Sarah suggests bringing Will's family back to their home, reasoning that the more people they have with them, the easier it would be to defend themselves should anyone else discover their location. Paul reluctantly agrees, and he takes Will to collect his family. Along the way, they are ambushed by two men. Paul kills them and accuses Will of having set him up. Will points out that he fought them as well and assuages Paul's mistrust.
