Dick Grayson incorrectly mentions the name of his parents' killer as Blade. The real killer was Boss Zucco.

Synopsis:
Dick Grayson performs at the circus of P.J. Farnum, which has been the target of mafia extortion. The ropes of Dick's trapeze are cut causing him to fall. Superman is on hand to save him. However, the distraction allows the criminal who cut the ropes and threatened Farnum to escape.

Superman then goes undercover to gain evidence against the mob. He disguises himself as Alonzo Scarns, a master forger. He is the recruited by the mob and brought to their leader Karl Lukaz. To earn his place, Scarns must murder Bruce Wayne. Bruce goes along with the plan and allows Superman to pretend to kill him.

Superman, as Scarns, earns the gang's trust. However, he is still unable to find hard evidence of criminal behavior. He suggests that Batman join him undercover in order to take advantage of his detective skills. Batman disguises himself as Doc Danner, then as Karl Lukaz himself. At a meeting of the mob leaders, Batman disguised as Lukaz exposes Superman in his Scarns identity.
