Superboy attacks Superman in an all-out battle to the death!
The trial of the Sidecar Bandits is disrupted when Superboy smashes through the wall to attack reporter Clark Kent. As Kent crashes through the wall, he takes the opportunity to change into his Superman costume. Superman rises to meet Superboy's challenge, though the elder Kryptonian is not quite willing to raise a hand to his younger counterpart. Superboy, though, doesn't hesitate. After unleashing three bone crushing blows, that put the Man of Steel down, the Boy of Steel departs. Superman feigns pursuit, but actually returns to the court room to resume his civilian identity. Once he's assured the security of his secret identity, Superman really does go after Superboy, but the Boy of Steel is long gone. While assisting a troubled motorist, Superman hears the telltale sound of Jimmy Olsen's signal watch. Superman follows the signal to the Grand Canyon, where he is ambushed by Superboy, and laid low by a Kryptonite missile. Superman awakens in Kryptonite chains. Superboy has gathered Olsen, Lana Lang, Lois Lane, Perry White, and Steve Lombard to serve as jurors in Superman's trial. Superboy reveals that he's really Pete Ross, Superman's boyhood friend. Ross used equipment, from one of Lex Luthor's, secret laboratories to draw Superboy to the present, from the past, then switch minds with him. Ross holds Superman accountable for leaving his son, Jon Ross, in the hands of a hostile alien race, the Nyrvn. Lane explains that Superman had no choice, as Jon Ross is destined to lead the Nyrvn, in Earth's defense, during the Millennium War. Hearing Lane's story, Ross' jurors return a unanimous verdict of "Not Guilty". Enraged, Ross threatens to kill them all if they don't change their verdict.
Meanwhile, in Smallville, Superboy, trapped in Pete Ross' body, makes his escape from Luthor's laboratory, Superboy travels to the Kent farm. in the hopes of using some of his old equipment to turn the tables on Ross. Unfortunately, once he arrives, all that remains in his old secret laboratory are a few books, a lamp, a dog whistle, and a few souvenirs. The dog whistle, though, might just provide Superboy with all the help he needs. Speaking for his fellow jurors, White reemphasizes their "Not Guilty" verdict. Undeterred, Ross decides to make them his witnesses to Superman's execution. Ross fires another Kryptonite missile at Superman. Using all his remaining might, Superman breaks the Kryptonite chains holding him, and plummets to the ground, just before the missile strikes. Ross flies into space to garner more Kryptonite. Lane urges the Man of Steel to make good his escape, but Superman is too weakened by the Kryptonite to move. Ross maneuvers a series of Kryptonite meteors into the proper trajectory to crash down upon Superman on Earth. Before Ross can complete his task, he is suddenly attacked by Krypto, the Superdog. Taken aback by the ferociousness of Superdog's attack, Ross is propelled back down to Earth, where he crash lands at the bottom of the Grand Canyon. Superdog frees Ross' captives. Lane and Olsen release Superman from his chains. Ross returns, but this time Superman, as well as Superdog, are ready for him. Ross surrenders without a fight. Back in Smallville, Superman switches Superboy and Ross' minds back into their proper bodies. Superboy immediately returns to the past, leaving Superman to ponder what to do about his old friend, Ross.
