Dead Within (2014)

Fear is Contagious

Set six months after a deadly outbreak has all but ended the human race, a man and woman have survived by isolating themselves in a remote cabin and never opening the door. Now they don’t have a choice. Starved for resources, they must confront the horrors that threaten them… but what’s inside may be even more toxic than what remains outside. When it all ends, this is what remains.
