The Red Hood, a hero from an alternate dimension, enlists the Dark Knight's help against the Injustice Syndicate, a team of supervillains who are doppelgangers of Batman's friends back home.

Batman comes to the aid of the Question, who has been captured by the balance-obsessed Equinox. Then Batman travels to the planet Ranagar to help Adam Strange repel alien invaders. Along the way Batman picks up a strangely depressed Aquaman who lacks his typical exuberance.
