Weird yummy goo erupts from the earth and is discovered by a couple of miners. They taste it and decide to market it because it tastes so good. The American public literally eats up the new dessert sensation now known as the Stuff, but, unfortunately, it takes over the brains of those who eat it, turning them into zombie-like creatures with no will to do anything but eat more of the bizarre substance by any means. It is up to ex-FBI agent David Rutherford and a kid named Jason to stop the spread of the mind-devouring dessert.
