Shaun is not quite your average twentysomething. Lacking any real ambition and drifting along in a job that he hates, he drives his long-suffering girlfriend Liz, up the wall.

Despite being a very decent chap, Shaun suddenly gets a very rude wake up call when the undead begin roaming the earth (or London's Crouch End, at least) and, with the help of his slacker chum, Ed, he must save Liz and his dear mum from becoming zombies! Well, that's if he can get out of the local pub.
