The evil Dr. Lunatic is taking the brains out of zombies and putting them into the heads of other zombies to create a race of super zombies! Only Bouapha possesses the cunning and resolve to put him on ice. Unfortunately, the vile doctor has quadruple padlocked his front door, so Bouapha is going to need to get the four Keys of Lunacy to open it, and Dr. Lunatic has entrusted those to his poker buddies, who happen to live in widely disparate regions of the world.
