Synopsis:
Batman and Robin tangle with an elusive costumed foe named the Grasshopper. The crook successfully steals the Batmobile during their first encounter. When the Grasshopper strikes again, he kidnaps Robin.

Batman deduces that the crook must be two different men in identical costumes. He follows one of them back to their hide-out, where the crooks attempt to lure the Caped Crusader into a trap. Batman doesn't fall for their tricks, rescues Robin, and successfully defeats both Grasshoppers.

When Batman recovers the stolen Batmobile, a mysterious individual called the Outsider reveals himself as the man who hired the Grasshoppers. Batman and Robin vow to be vigilant against future attacks by their unseen enemy.
