Mickey Mouse enters Pluto in a ritzy dog show. The two arrive there in a makeshift wooden car. While Mickey grooms Pluto, Pluto starts swooning over Fifi the Peke. When Pluto is called to the judge's stand, Mickey quickly retrieves him. Things don't look good for Mickey and Pluto after he attacks the judge (due to him being rude to Pluto), resulting in the two getting kicked out. Upon hearing trick dogs coming onstage to perform, Mickey decides to reenter Pluto in the dog show as a trick dog, but Pluto is nervous about the idea. When a photographer attempts to take a picture of the trick dogs, the camera's flash powder ignites a curtain, causing a fire to break out in the building. Fifi gets stuck under a fallen microphone stand. As Mickey is about to go back in with Pluto as a roller skating dog, a crowd of people and dogs run out. Pluto hears Fifi and bravely goes in, still wearing his roller skates. Mickey tries to follow, but is stopped by falling debris. After hitting a column and narrowly avoiding a collapsing part of the floor and a falling wall, Pluto skates his way across wooden beams and saves Fifi just before the floor that she's on gives way. They escape the burning building by crashing through a window and land on a drain pipe that folds down like a spring and launches them out onto the street. Mickey and the others gather around Pluto and the judge awards Pluto with a medal as everyone cheers for him, hailing him as a hero. Pluto then uses his ear to pull Fifi behind the medal, presumably sharing a kiss.
