When a crimewave plagues the shopkeepers of Springfield, three men vow to stop ne’er-do-wells in their good-for-nothing tracks. Three mere mortals will stare villainy in the eye and dare it to blink. Three vigilantes, who comprise…the Merchants of Vengeance. Be there as an alliance is formed, a bond is forged, and (as usually happens to such bonds and aforementioned alliances) a confidence is betrayed! Then, witness the cream-filled fury of Pieman (actually Homer Simpson) when an evil doppelganger seeks to tarnish his indignant and indulgent identity. And Bart and Lisa prove that a little imagination is a dangerous thing when they go on a sensational rampage through the streets of Springfield.
