Synopsis for Superman and Batman: "Inside the Mafia Gang!"
In order to break up a Mafia family headed by Karl "Big Uncle" Lukaz, Superman and Batman go undercover as gangsters. The Man of Steel poses as a forger and before he is allowed in the gang, he has to kill Bruce Wayne. Faking Bruce's death with Batman, Superman is allowed in the gang and shortly after Batman followed suit, as part of their plan.
When the heroes decide it is time to replace the big boss of the gang, Superman kidnaps Lukaz and imprisons him at the Fortress of Solitude. Batman masquerades as Lukaz, hoping to nab the entire gang, but a fall he has taken causes him really to believe he is a Mafiosi. The effects are too severe as he unmasks Superman at a Mafia meeting and exposes him to Kryptonite.
