A rock like alien lands on Earth looking for sustenance. What does it eat? Intelligence! One touch of the rock and it sucks the smarts, if you have any, right out of you. Dr. Belinda Garland studies the alien rock to harness its power. However the evil Amazing Jacques and his co-hort, The Spiderwoman, plan to use the rock's brain sucking power to rule the world.
