While chasing Smiley Dix and his gang the Batmobile drives over a bridge that collapses. Batman is injured in the crash, and the Batmobile is destroyed. While recovering from injury, Batman's mobility is limited, so he constructs a new Batmobile with many technological advances. Then with Robin doing the leg-work, Batman tracks down Smiley Dix and apprehends him with the help of the new Batmobile.
