Lieutenant Frank Drebbin returns to save the day once again. This time he's out to foil the "big boys" in the energy business. A top scientist (Dr. Meinheimer) is about to publish his report on energy supply for the future. Things don't look good for the traditional suppliers; oil, coal, and nuclear. To save their industries, the suppliers kidnap Meinheimer and replace him with a decoy with a more favorable report. Jane, the doctor's secretary, is Drebin's old flame. Their passionate love affair is thus rekindled.—Rob Hartill
