A world with no adults, and in order to survive they form groups with other people they think will be loyal and protect... But then there are the people that don't belong to any group, which usually end up hiding or living in the woods, trying to survive with almost no food or water. All that while the groups rob and bully those weaker than them. But they all don't realize that instead of fighting each other, they should be fighting alongside one another... but against who?
