"Superman, in his civilian guise of Clark Kent, is going to interview actor Ronald Jason, however Jason suddenly splashes him with a chemical that burns off his clothes revealing that Kent is really Superman. Jason however, reveals that he is an alien named Dur from a planet in the Sirius system. He explains that on his world the Tontor-1 was assassinated, and in order to protect himself he teleported himself to Earth, however he believes that he is being pursued by an enemy agent from his home world and sought out Superman for protection. Superman then flies Dur to his Fortress of Solitude where he'd be safe.\n\n\nMeanwhile, in the Batcave, Batman is visited by another alien named Tiron, who tells Batman that Dur is a criminal who escaped to Earth. The two hop in the Batplane, but when Batman suggests that they seek out Superman, Tiron tells him that he is aware that Dur has tricked Superman into helping him. So instead, Batman seeks the help of Supergirl. The three fly to the Fortress of Solitude to apprehend Dur, but Superman returns to fight them off.\n\n\nWhile Batman and Supergirl are otherwise preoccupied, Superman flies to Gotham City and recruits the help of Batgirl to help him protect Dur. Meanwhile, suspicious of what's going on, Jimmy Olson and Robin team up to learn what they can about the aliens. When viewing their secret scanning devices, they learn the secret of the aliens, however before they can warn anybody they are hit with knock out gas.\n\n\nMeanwhile, at a new hiding spot, Superman and Batgirl fend off the attacking Batman and Supergirl until suddenly Tiron collapses. Checking him out they find out that he is not an alien at all, but Ronald Jason in disguise. Jason explains that he was terminally ill and was playing both the parts with the help of his late brother, scientist Desmond Jason's inventions to facilitate the ruse. With his explanation complete, Jason dies knowing he had played his greatest role. Afterwards, the heroes insure that a statue is put up in a museum commemorating his memory."@en .
