no sanctuary

A man with a beard and disheveled hair appears in a dimly lit, industrial setting, then is seen crouching behind a chain-link fence as an explosion erupts in the background, followed by a scene of him being attacked by a zombie in a warehouse, then a woman in a cap looking on in a wooded area, then a group of people in a dusty courtyard with a man in the foreground, and finally the man with the beard smiling in a sunlit outdoor area.
