Colonel Colby's Show of Wonders is in Metropolis. Among those performing in the sideshow is Thora, the world's strongest girl performer. The cub reporter is among those who pays the twenty five cents admission. During the show, Jimmy is suspicious when the slender girl manages to lift a one ton weight.
The final act features a prehistoric caveman found in the Arctic. The frozen figure still holds onto his iron spear. The cub reporter is well aware that in the Stone Age, the cavemen only had stone heads on their spears. After the show, he confronts Colonel Colby, and identifies himself as a reporter of the Daily Planet. When Jimmy threatens to expose his swindle, the Colonel warns him that he'll be sorry. Back at home, the cub reporter casts a worried eye towards his valuable Superman souvenir collection. The Man of Steel recently gave him an unused tear-gas bomb from the time he caught the Tear-Gas Gang. With it, Jimmy could set a trap against anyone who tries to enter his apartment uninvited. The next moment finds Jimbo tripping over his tool chest, and dropping the tear-gas bomb. The fumes get into his eyes and nose... "cough!" He is unaware that Colonel Colby has followed him to his apartment building by automobile. The Colonel watches, thinking about offering Olsen a bribe, and then gets a better idea. He watches as Jimmy opens the window, and sees that the cub reporter is now temporarily blind.
As Jimmy talks on the phone with Perry White about his story, and needing a taxi, Colonel Colby sees his opportunity. Outside, the cub reporter hangs onto a light pole and calls out for a taxi. Disguising his voice, the Colonel leads the blinded reporter into his... er... taxi. Now out of town, Jimmy is in for a surprise. It is Colonel Colby, not a taxi-driver who is at the wheel, and he is taking the cub reporter for a ride. His Superman signal-watch won't work because the Man of Steel is currently at the center of the Earth, where the ultra-sonic signal cannot reach him. As he photographs the Earth's molten core with a camera encased in a super-hard, fireproof plastic case, Superman is unaware of his pal's peril, but another pair of super-ears have received Jimmy's signal. As Linda Lee at Midvale Orphanage changes clothes, the ruthless Colonel Colby is about to shove Jimmy Olsen off a bridge over a gorge.
As he drives away, the Colonel doesn't see the arrival of Supergirl, and the cub reporter striking his head against the bridge in the fall. When he recovers, the cub reporter tells his story. If she were to pick up Colby, the Colonel would simply deny the story, and with Jimmy blind, he couldn't prove it. Making an important decision, the Maid of Might decides to tell her cousin's pal that she is Supergirl. Jimmy has never heard of such a person. She tells him that she's the Man of Steel's cousin from Krypton, who came to Earth. Her cousin wants her to remain secret until she learns how to use her super-powers to the best of her ability. When Krypton exploded, a large section with a town on it was set free. The ground beneath the town turned into Green Kryptonite, but a scientist had sheets of lead foil to stop the radiation. Years later, the daughter of Zor-El was born, and her father was the brother of Jor-El, the Man of Steel's father. The time came when meteors destroyed their lead shield, and the radiation would kill them all. With his space-rocket completed, Zor-El sent Kara to Earth.
On Earth, she would meet her cousin Superman, and gain super-powers as Supergirl. Here she is, in answer to the summons from Jimmy's signal-watch. The cub reporter doesn't believe a word of it. He wasn't really falling or in any danger because the Colonel is undoubtedly pulling another hoax on him. Colby wants him to believe that there's a Supergirl. If he were to tell Perry White about it, he'd be fired from the Daily Planet. The Colonel's other hoaxes would never be exposed, but he won't fall for such a scheme. In order to convince Jimmy that she does have super-powers, the Maid of Might uses her x-ray vision, and informs the cub reporter that he has exactly seventy-five cents in his pocket. This is true, but she's probably Thora, the strong girl who works for Colonel Colby, and saw him making a change of a dollar when he paid for admission. The Maid of Might tries again by having Jimmy hold onto a tree, while she slices the trunk with her super-hand. He should believe that she's Supergirl when he feels it sway and hears it fall.
The cub reporter figures that this was probably prearranged and she was able to make it fall with one push. Now, she flies with him through the air, and he can feel the wind. Jimmy figures that it's some sort of wind machine, and that she's standing on the ground while holding him in her arms. Now in the Sahara Desert, she asks him if he can feel the change in climate. The cub reporter figures that they must have a lot of heat lamps on him right now. At the North Pole, Jimmy feels the cold, but figures that they are inside a deep-freeze refrigerator. Unfortunately for Supergirl, she can't do any super-stunts in front of other people to convince Jimmy. No one on Earth must suspect that she exists, except for Superman's pal. The cub reporter plans on exposing her and takes out a small transistor-radio he carries to pick up news for his job.
Now in Metropolis, Jimmy has tuned in the Metropolis Rodeo Show, but only so he can hear it. If she has super-powers, she should be able to tell him what act is on now. Using her telescopic-vision, she tells him that the announcer is describing an Indian War Dance, and asks if he believes that she has super-hearing. The cub reporter figures that the Colonel gave her an ear-trumpet to pick up the radio's faint sound, and enabled her to hear it. As Jimmy figures that Colby's sideshow Strong Girl can't pass herself off as a Supergirl, the Maid of Might picks up a pair of scissors from Midvale Orphanage. She's finally thought of a way to prove that she's Supergirl. He can feel that this is her own hair and is asked to try and cut it. The hair is indestructible just like the Man of Steel's hair. The next moment finds the radio reporting and Supergirl's telescopic-vision watching a cowboy getting his foot caught when he roped a steer.
Unless she acts fast, the cowboy will be a goner. Taking the scissors from Jimmy, she uses her super-breath to cool the metal so that it won't melt from air-friction when she throws it away at super-speed. No one at the rodeo will be aware of what happened when the scissors cuts the rope and saves the cowboy. The cub reporter wants to know why she took the scissors away from him after it failed to cut her hair. When she says it's gone, he figures that it was a trick pair used to fool him about her hair. Why did she throw the scissors away instead of using her heat-vision to burn the rope? If only she were as experienced as her cousin, but as it is, she'll never convince Jimmy that she exists.
Her super-hearing picks up the loud sound of Superman boring up from underground. His scientific assignment has been completed, and now he can help his blind pal now. A puff of her super-breath works the button on Jimmy's signal-watch, and brings her cousin to the scene. Before he arrives, Supergirl heads for Midvale Orphanage, and Superman greets Jimmy. Recognizing his pal's voice, the cub reporter tells him about Colonel Colby and his sideshow. Back at the sideshow, a punch from the Man of Steel's fist shatters the ice surrounding the "caveman", and reveals it to be a lifelike dummy. The audience will be getting their money back. His x-ray vision reveals the face beneath the rubber mask as "Big Con" Colby, wanted for the killing of a previous witness who saw through his other cons. Days later, at Midvale Orphanage, Linda Lee uses her telescopic-vision towards Metropolis, and sees that the cub reporter has gotten his sight back. She smiles when Jimmy tells her cousin about Colby trying to fool him, and make him believe there really was a Supergirl. As far as Jimmy Olsen is concerned, she doesn't exist.
This story was reprinted in Action Comics #443 (November, 1966).
On page one, the world's strongest girl performer is referred to as "Thora," but on page five, Jimmy refers to her as "Thara".
When he's not drinking something, the cub reporter is stumbling over something in his Superman souvenir collection.
The citizens of Argo City managed to take advantage of their lead, and foiled the deadly radiation for a time.
In theory, Supergirl could have told Jimbo if he was wearing boxers or briefs, but Jimbo probably would figure that she already had a look when he was out cold.
The cowboy caught a bum steer, but Supergirl saved the day, and lost the cut.
When the Man of Steel changes direction to answer his pal's call, he is no longer carrying the camera.
Colonel Colby's audience must not have liked to be made dummies of by a fake caveman, and they would no doubt have caved his head in.
"Big Con" Colby may be a crook, but he sure knows where to find those realistic false rubber masks.
