The movie starts with a family leaving their city in fear to the woods. There seems to be an entity that is watching them. The family has the mom, dad, brother and sister. Some sort of crazy event has happened and that is why they are in the woods. The father and son go on a look out and the mom and sister stay at their camp. Once the father and son return the two women are dead. Presumably killed by men with guns they saw at a gas station. The father and son run away. And later on the son dies leaving the dad the only one still alive. He then remembers that he killed them, after finding a house with other people. He killed them as well as his family, and because of the guilt he sits on the floor and shoots himself in the head, ending the movie. I saw this a few years ago and have been trying to remember the name but I just can't. I can't get the movie off my mind. I just need to know the name, I am 100% serious I have been trying to find it ever since I remembered it.
