A sex crazed doctor named Dr. Montana prepares to give a patient named Mr. O'Brien a brain x-ray. Dr. Montana leaves and enters the control room, continuing to have sex with his bombshell nurse as Mr O'Brien looks on through the window, somewhat confused and amused. The nurse's butt continuously hits the x-ray machine while they have sex, subjecting Mr. O'Brien to constant bombardments of radiation for the next 20 minutes. The radiation fries Mr. O'Brien's brain, killing him.
