Paul (Joel Edgerton) lives with his wife and seventeen-year-old son Travis in a boarded up house in the woods. They had to take the grandfather, who is clearly sick with some disease, out to the woods, shoot him in the head and burn his body. Then, a stranger shows up named Will (Christopher Abbott of GIRLS, THE KILLING), who says he thought the house was abandoned. Paul doesn't trust him at first but then agrees to help him retrieve his family from 80 miles away. He has a wife and a young son. At first they all get along, but when their family dog disappears in the woods there's a problem. Travis wakes up one night to find the front locked door open and hears the dog outside. And it was probably the little kid who opened the door. Soon he gets the disease and there's a confrontation between the two families.
If this all sounds familiar it's because it is. I can't tell you how many of these types of movies I've seen in the past decade, from "end of the World" to "bomb shelter movies". The only threat is this disease and there's not even any mutants or zombies they transform into. I was bored.
