Police authorities in Chicago are seeking serial killer "Georgie Porgie." His M.O. is to murder blondes with a "cheap" reputation. He was thought to have "gone south for the winter" after a killing in Tennessee. But he has returned to Chicago and kills a woman in the middle of a strip club. Georgie Porgie is somewhere on the Illinois Tollway. However, the manhunt is complicated by a missile convoy moving through the Chicago area.
