You are Slobodan, a man living in a post-apocalyptic world full of zombies. You accept an offer to take a girl, Ana, who is immune to the zombie infection, to a group of revolutionaries who may be able to create a vaccine against the infection, and in return they will reward you richly. You have promised your partner that you will bring the girl to her destination, but before the most dangerous part of the road you come across a hidden and successful community surrounded by walls, where a normal and safe life is currently being lived, and one of the residents is your brother.
