In the realm of King Arthur, trouble ensues when the Singing Sword is stolen by the infamous Black Knight Yosemite Sam.

Reluctantly, court jester Bugs Bunny is assigned the mission by King Arthur, facing considerable consequences if he fails.

Upon infiltrating the castle of the Black Knight, Bugs encounters a dragon, companion to Yosemite Sam, suffering from a cold-induced sneezing fit.

When Bugs wonders aloud why it is called the Singing Sword, it starts humming "Cuddle up a Little Closer, Lovey Mine" and causes Sam to wake up from his nap.

As a result, Stanley scorned the U.S. film industry and relocated to France, where despite becoming a national star still nursed a bitter grudge against Bugs, culminating in the episode's plot.
