An alien army of killer mutant zombie bums is headed for Earth. Their mission? Total zombie-bummification of the planet. Who else could be behind a plan to stink out the entire solar system but the Great White Bum? Luckily, the dastardly derriere holds no fear for Zack. Armed with little more than a squeezy bottle of tomato sauce, Zack gets set to follow his destiny and save the world. It's dirty work, but someone's got to do it!

A hilarious, comic action thriller, pun-packed and pacy!
