Jerry and Nibbles are two mouseketeers who decide to help themselves to a lavish banquet, which Tom has been ordered to guard from the King's Mouseketeers with his life; failure to do so, otherwise he will be executed. Jerry and Nibbles enter the castle hall through a stained glass window, through a suit of armor, and by parachuting down to the table. They unsuspectingly catch Tom's attention by showering him with champagne.
