Tom chases Jerry through the sidewalk as the title cards and credits are shown. Jerry gives Tom the slip and Tom turns around the other way in anger. Jerry stops short when he sees a lion's mouth, but it is only an ad for a local circus. Seeing Tom approach in fury, Jerry sees no alternative but to jump into the lion's mouth. He disappears as Tom pulls up in bewilderment. He pulls some of the advert off and reveals that Jerry was lucky enough to hit a hole in the fence and is disappearing into the distance.
Tom follows Jerry into the circus and Jerry hides behind a post as Tom dashes by him. Jerry laughs and walks away when he is splashed with a tear from an elephant, who has stepped on a tack. Jerry removes the tack and the elephant hangs back, afraid of Jerry (as he is a mouse), when Tom approaches him and the elephant picks him up with his trunk and beats him like a drum on the stool. Jerry shows the elephant the tack and the elephant looks at its foot, and finding nothing there, hugs Jerry.
Tom pulls up a ladder and swipes the mouse, but meets the elephant's anger, who uses its trunk as a hammerhead. It then returns to hugging the mouse. Tom emerges from the ground, dazed, and then falls unconcsious.
Tom is sitting behind a stool, annoyed, as the elephant and Jerry participate in the circus. Jerry and the elephant dance in the spotlight and pass a ball back and forth. Tom aims a slingshot at the ball and busts it. The elephant looks for its friend in concern and Tom ascends a high-rise ladder to reach the mouse, who is hanging onto the high wire by his feet. Tom slicks across the wire and stomps on it repeatedly to bounce Jerry into his hands. He then walks over the wire and encounters the irate elephant. It pulls both of them all the way down to the ground with the high wire, pulls the mouse into its trunk via suction, then releases the cat.
Tom chases Jerry into a ladder that leads to a diving board. Jerry sees the bowl of water down and holds back until Tom approaches and he can see no alternative. Tom barely misses the mouse and ends up diving himself. Jerry makes a successful dive, and the elephant happens to drink all the water, taking Jerry away with him. Tom sees the empty bowl and points down in dismay before impact. Tom crashes through the ground with such force he falls all the way into hell! The devil takes him back up to the surface and throws him out.
The elephant is playing with Jerry, throwing him up into the air and then sucking him back to its trunk. Tom sticks out a stick with a pepper shaker on one end and shakes pepper into the elephant's mouth. He elicits a gigantic sneeze which throws Jerry miles and miles from the circus. Tom runs backwards with a baseball glove to catch the mouse, but somehow the elephant has appeared. He runs up the elephant's leg and perches himself to catch the mouse, but the elephant rolls up its trunk and throws the cat off him. He then catches the glove and also catches Jerry, and proceeds to hug the mouse again.
Jerry and the elephant are now leading the circus parade, with Jerry playing the bugle and the elephant playing a very loud drum which causes the cymbals to rise and then crash together. Tom is in a manhole looking to make mayhem of the parade. He has connected some dynamite to a detonator and is looking to blow up the elephant when it steps on the switch. The sheer gravity of the sound, however, pushes the dynamite into Tom's manhole without Tom seeing it; therefore, it blows up Tom instead when the elephant steps on the detonator. The parade continues past as Tom waves a flag that says "The End."
