Mysteries of the Superman Awards! Superman is scheduled to appear at the 1968 Superman awards as himself, but is also slated to escort Lois Lane there as Clark Kent... Bruce Wayne is also attending, meaning that he cannot substitute for Clark
The Evil of Alpha and Beta Supergirl exposes herself to Gold Kryptonite in hopes of destroying her powers, thus preventing the bomb at Stanhope from detecting them and detonating. Then she assumes her Linda Danvers identity, and tricks Alpha and Beta into letting her inside the barrier. The two female terrorists put her to work in a lab assisting David Carew, whom they have captured. Carew tells Linda that Alpha and Beta have told him he is destined in the future to create Noricon, a vaccine against all diseases, so they are forcing him to try and discover it now. Linda spurs Carew into creating a diversion that allows them to escape the lab. When David sees the Linda Danvers robot, Linda changes to her Supergirl costume, revealing her double identity and her plans to him. They head for the bomb, intending to dismantle it, but Alpha and Beta deduce their destination and come after them. Meanwhile, Superman wonders why Supergirl has not kept an appointment to meet him at the Fortress of Solitude. Seeing her plight with his super-vision, he flies to Stanhope and intends to crash through the barrier. Supergirl shouts a warning to her cousin, but he is moving too fast to stop himself in time.
