It's a hot summer day and all Dane wants to do is get through his Saturday morning shopping trip at the mall. Instead he's caught up in a sudden outbreak of zombies, and finds himself desperately trying to survive both the zombies and his new companion, surly frozen yogurt stand employee Killian.
Zombie movies and video games have nothing on a real-life attack, and Dane's general feeling of uselessness isn't helped any by the fact that Killian is efficient and looks good doing it. Fortunately for him, Killian has a soft spot for nerds and knows that the only way they'll survive is if they stick together.
