Batman and Robin witness an accident at the opera which kills two actors. The star of the show Colin Vanning believes that someone was trying to kill him. Batman investigates and does discover a killer. He acts to prevent several more accidents on the stage. Finally he discovers that Vanning himself was the killer. Vanning was already deathly ill, so he wanted to go out in an uproar. As his final act, Vanning commits suicide by singing a note which causes his heart to burst.
