In a world overrun by zombies, these two are perfectly evolved survivors. But now, they're about to stare down the most terrifying prospect of all: each other. A shy student trying to reach his family in Ohio, a gun-toting bruiser in search of the last Twinkie and a pair of sisters striving to get to an amusement park join forces in a trek across a zombie-filled America.
