A half-million gallons of oil fed spectacular flames at Los Angeles' "El Segundo" refinery. The first was started when a bolt of lighting ignited a wooden cover to an oil reservoir. Enormous black clouds of smoke rise from the ground. Spectacular balloons of dense black, black smoke are thrown from a burning lake of oil. Fire fighters stand helplessly looking of the blaze. Various shots of fire mixing with smoke. Aerial shots show the train of smoke moving through the sky causing massive air pollution.
