 Circus clown Felix Heidemann marries Lisa in a whirlwind. Part owner Jerry Franklin, who is also in love with Lisa, is taken aback. In her exuberance Lisa accidentally releases a tiger that seriously mauls Jerry. Four years later, Lisa has married wheelchair-bound Jerry out of pity, but she did not divorce Felix. Another clown, Tim Durant, tries to oust Felix from the circus by supporting the other owner, Judd Curtis, in his bid to buy out Jerry. Felix consults Perry Mason, and everyone goes to the circus that evening, including Lt. Tragg. During Felix s act, the main attraction, one stunt involves blank cartridges, but one shot fired was a live round that kills Curtis. Tragg arrests Felix, and Perry must prove him not guilty.
