Shannon is sixteen and a zombie "fanatic", as are many of her friends, so it's no wonder that she's fully prepared when a large-scale zombie invasion begins. Her brother is also in the air force and flies helicopters, so she has him to come help them out. However, when her brother can't get away from his base and Shannon and her friends are stranded in the middle of a zombie infested town, soon they discover that there's a big difference between knowing how to survive a zombie apocalypse, and actually being able to do it.
