Ares hatches a plan to overthrow sister Athena's city-state and demands an ultimate weapon of destruction from Hephestus, who creates the Armageddon Bow. The weapon is so deadly and accurate that Athena comes to Hercules to help her find and destroy it.

The gang visits an old age home, where they're each assigned a senior citizen to befriend. In an effort to connect with his oldster, a malevolent old Griffin, Hercules accidentally reveals the treasured Diamond that the Griffin had been guarding for decades - and the King of the thieving mountain gnomes, steals it.

Taking place after the Hercules movie, Hercules is moving his stuff from Phil's old place to his new place. While looking through the old stuff, Meg finds Herc's old yearbook. Hercules, not wanting to be embarassed, takes the yearbook, and hides it. Meg finds it, and we are shown a clipshow of past episodes, ending with a musical number.
