Mickey Mouse, Donald Duck and Goofy are working at a car service station, working together to fix a broken car. Soon Pete (Disney) comes by, and angrily demands that they fix a squeak (to the tune of "Yankee Doodle") in his tire. He tells them that if they don't get the job done in ten minutes, they'll have their heads cut off. Scared by the thought, they quickly get to work. Slight gags show them to be inept at car repairing, including scenes where Goofy and Donald pull each other through the car's lights, Mickey getting stuck in a tire several times, and Goofy smashing pieces of the car's engine.
