Tom chases Jerry into the then-brand new Metropolitan Opera House, where Georges Bizet's Carmen is being performed, but is quickly thrown off the premises by the guard. Tom attempts to get in by disguising himself as a wealthy gent, but is tossed out once again by the guard. Tom tries once more, dressed as a musician and carrying a large string double bass case, successfully bluffing his way through by whistling a few notes of the Toreador Song and successfully makes it to the opera. He opens a double bass case, a cello case, a viola case, a violin case, and finally a violin.
