Moe is on trial for assaulting Curly and Larry with an ax. Moe relates how Curly and Larry took him on a hunting trip for his nerves. Out in the woods they confronted a bear which Curly and Larry stunned, and thinking it was dead, threw it in the back of their car, where it came awake, tossed Moe out and drove the car into a tree. The judge finds Moe not guilty and Moe promptly goes after Larry and Curly again with the ax.

The trio are employed as handymen in a recording studio. While not doing their work, they hear a recording session as a woman sings "Voices of Spring." Impressed by the operatic virtuosity of this stunningly beautiful soprano, Curly lip syncs, as the other stooges dress him as a woman. Curly (in drag) is "heard" by the radio host. Moe dubs Curly "Señorita Cucaracha," and the trio are hired to sing professionally on the radio, but must also appear at the home of the radio show's sponsor for a party.
