We didn't even see the herd of zombies when we walked to the park that day. It would've been nice to know. Charlie, Lily, and Arthur never would've thought that their worst nightmares would come true: pants-eating zombies. No, really. That never occurred to them. Now as the apocalypse ensues around them, the three are stuck running around with an old dude who predicts the future, a girl with a red bush of curls on her head, and a not old dude who's addicted to NyQuil in an attempt to keep his pants. But as the crackhead situation starts to fly off the handle, the friends start to turn on each other along with unlikely romances leading to rivalries, and impending doom. Will they all leave with their pants on? Or off?
