From Ignition: The Earth is under attack by a horde of Alien Brain… uh…Thingys! Humans, succumbing to ray-guns, mind-control, and shiny flying saucers, have failed to defend their planet and let it fall easily into the clutches of the Big Brain and his army of Brain Thingys. The only hope left for mankind is three Teenage Zombies that have arisen from a graveyard disturbed in the invasion. The undead trio ignores their normal human victims in favor of the pulsing pink brains they see EVERYWHERE - all the while being lured to the ultimate lunch: THE BIG BRAIN!
