Ski-hi has an auto. He loads it up with nitroglycerin and takes a trip through the clouds. A mule kicks two of his enemies on him as he is repairing the car. Ski-hi jumps in and starts off with the two on the radiator. The car goes through a fence and knocks off a fat person sitting on it, goes through a mountain of granite, falls down a precipice through the roof of a house, but Ski-hi is finally captured and dragged about by his pigtail.
