Lance, a young computer technician, is hired to fix a supercomputer in a crumbling, eerie castle. The job goes sideways the moment it's done — his client turns out to be Dr. Nero Neurosis, a disembodied brain with plans for world domination. After Lance makes the mistake of calling Nero average, the doctor unleashes his unhinged servant Fritz to hunt Lance through every corridor of the castle. The only way out is through Dr. Neurosis himself.
