When a circus arrives to town, it features its famous attractions including "''The Great Barko and His Famous Acrobatic Dogs''". And under the commercial posters an advertisement stands, titled "''Dare Devil Dog Wanted''", advertising a job for Barko's new dog-acrobats, under the condition "''Must be Fearless!''". This attracts both Droopy and Spike's attention to apply for the job. Satisfied with the reply from the two dogs, Barko decides to put the situation on the competitive basis: "''The one that gives me the best performance in Physical strength and Courage, gets the job!''", to which the dogs agree. During every tryouts – "''see Simpson the Strong Man''" test of strength, High striker, "''Pop the Balloons''" shooting, "''See a Sawing a woman in half''", "''The Flying Human''" flight test with a propeller on the head, riding a car through a solid brick wall, "''Marksman''", juggling, riding on a motorcycle through a ring of fire, Trapeze, Tightrope walking, figure skating and "''Human cannonball''" shooting out of the cannon – Spike tries to outperform Droopy and sabotage his performances, to which he fails every time and gets himself injured a couple of times. During Droopy's final act, Spike tries to sabotage the other again, by burning his foot with a matchstick. But this leads Droopy to perform faster, leaving the audience to applaud and gives him a minor burn on the foot. Impressed with Droopy's successful performances, Barko hires him to be one of his Acrobatic Dogs. Outraged, Spike chops one of the trapeze poles to bring it down on both Droopy and Barko, but instead, it lands on Spike, leaving him the loser.
