Batman and Robin arrive at a penthouse party for a visiting Indian rajah when a mysterious box-kite begins dropping tear gas bombs on the party-goers. This serves as a well-enough diversion for Kite-Man, using his jet-kite, to steal the rajah's ruby. Although Robin manages to lasso the villain's leg, Kite-Man continues his escape. The Boy Wonder loses his grip and falls safely into a rooftop water tank.
