The Day follows a group of five survivors in a post-apocalyptic world as they travel through a bleak environment in an attempt to find food, shelter, and a safe place to stop running from tribes of savage cannibals that roam the country-side. They hope to plant two jars of seeds that they either stole or found during their journey. There was at some point twelve in their group, but it is not known how the others died or how long the remaining five have been on the run.
