Sam, Arty and Emmie have barely got over a recent zombie infestation when their sleepy little town finds itself the victim of an alien invasion! But the aliens are very small and kind of, well, cute looking - how dangerous can they be? SPOILER ALERT: they're VERY dangerous. And when they disintegrate the mayor with their ray guns it'll be up to Sam, Arty and Emmie to save the day. Again.
