Synopsis:
Batman has criminal Ralph Stuart under surveillance. The crook turns himself in after witnessing a murder committed by four ninja assassins. Batman locates the victim and the man who put out the hit, Mugs Clifford. He then tracks down the assassins who used a technique known as the vibrating palm. Batman is one of the few people in the world who knows the move.

Following the capture of the assassins, Batman seeks out Kirigi, the master who taught him the move. The master makes no moral judgment concerning others than he trained, but the Batman does.
