Synopsis for "Superman and the Purple Plague"
Clark rides an ambulance from the police headquarters, to pick up a patient, a man in a stupor, from which he can't be aroused. The doctor on duty acknowledges he's never seen anything like this.
The disease quickly spreads as a plague, killing dozens of people. Prof. Henry Travers, a scientist who's a friend of Clark, finally finds a cure to the disease, but then he's suddenly knocked out and abducted by the Ultra-Humanite's henchmen. Superman hurries after the crooks, but they throw the scientist off a cliff to get Superman off their backs. Superman manages to save the scientist, and soon learns that the Ultra-Humanite is behind the artificial plague. Unfortunately Travers' first formula fails to cure the plague.
Superman confronts the evil old mastermind, but is injured by Ultra's electric-gun. The Ultra-Humanite attempts to electronically mind-control Superman into distributing more of his Purple Plague, but Superman was only pretending to be mind-controlled, and he destroys the villain's stockpile of plague serum. Ultra tries to shoot Superman again with his Electric-Gun, but this time Superman pulls him in front of the weapon, which seemingly kills him.
Dr. Travers soon develops a workable cure for the Purple Plague, and the epidemic is stopped.

Chuck is riding down a gully, when he is lassoed and pulled off his horse by two roughnecks! They tie him up and start exchanging his boots for another, fancier pair. Then they ride off, leaving Chuck very confused. Luckily, he trained his horse to untie knots, so with Blacky's help, Chuck is soon free. Making a mental note of the direction the boot bandits took, Chuck continues on to the small town of Deposit Gulch.
A crowd is gathering around the sheriff's office in town as Chuck approaches. The local shopkeeper spots him and points him out as one of the gang that robbed his shop and killed his employee, the boots on Chuck's feet identified him as such, as they were the same boots that were just stolen. Chuck manages to fight his way past the crowd, back to his horse. He rides out of town fast... back towards the gulley where the two bandits attacked him.
Chuck follows the tracks the bandits left to the bank of a mountain stream. Climbing atop a ledge, he soon spies the men pass down below.

Clip Carson is hired by a man named Colton, to help him deliver ivory to the African coast, where a steamer awaits. All other parties he sent with the ivory have disappeared at the hands of Wolf Lupo, a renowned criminal. Clip agrees to help, and almost immediately the attempts on his life begin. One burly man in a bar tries to knife him, but Clip outmatches the brute easily. He and the natives hired by Colton hike through the jungle, carrying the ivory in a crate, and when they set up camp for the night, someone releases a deadly cobra in Clip's tent. Luckily, his unerring aim hasn't failed him yet, and the snake is dispatched with a single shot.
The next day, the group enters dangerous territory, where they are met by the cannibalistic Wanangi tribe. Clip speaks in their native language, offering them a gift of harmonicas (Which he brought along just in case he needed a bargaining chip) for safe passage. The chief is delighted with the pleasing music the harmonicas make. He gladly accepts these gifts and announces Clip and his group to be friends to the Wanangi.

Synopsis for Tex Thomson: "The Zombies (Part 1)"
Tex Thomson and his friends, Bob and Gargantua, head to Egypt in search of Mr. Barryless' son, Bart, who was leading an expedition, when his letters abruptly stopped coming. Tex finds that Bart's expedition has been attacked by the Fuzzy-Wuzzy tribe, famous for turning unsuspecting enemies into mindless zombies. A tribal warrior attacks Tex and crew, chasing them over a gorge where the rough landing sends them into unconsciousness. When they awaken, none other than Bart Barryless himself is standing before them, also being a helpless prisoner of the Fuzzy-Wuzzy. He explains that the tribe's chief was planning to use the zombie serum to turn all of the world into his mindless slaves. The rest of Bart's expedition had already been given the serum and made into a zombie. The only way to counteract the effects was with salt, which he had none of. But Tex does! He has a package of salt in his knapsack!
Tex, Bob, Gargantua, and Bart are forced to line up in front of the chief. Each of them secretly hid a lump of salt in their mouth, to swallow immediately after being administered the serum.

Synopsis for Three Aces: "Murder in the Air"
During a nine-plane bombing run, Fred, one of the pilots, loses control and crashes to the ground a flaming wreck. Fog, Gunner, and Whistler believe Fred was sabotaged, and begin investigating. They find out there were traces of battery acid on Fred's flight suit. Days later, at the park, Fog calls Gunner and Whistler over to the bushes, where they eavesdrop on Jeffrey, the plane mechanic, and Bell, the wife of the deceased, making out. They talk about how soon they'll have a fortune to themselves. This raises the Aces' suspicions. Could those two have had anything to do with Fred's death? They'd need to test them to be sure.
The Three Aces visit Jeffrey in the hangar. They talk about the death of Fred, whom Jeffrey called a friend. Gunner lays the bait at Jeffrey's feet by casually mentioning that the detective in charge of the case believes it was murder. Whistler and Fog add to it by saying how they heard traces of battery acid were found, and how the police already had a pretty clear idea who was behind it. The Aces laugh it off as they leave, but Jeffrey suddenly turns pale.
The Three Aces bring a police officer along as they drive to Bell's apartment. They sneak inside and hide themselves as Bell and Jeffrey discuss what he heard in the hangar. The police were onto them! Jeff tries to convince Bell to leave with him, to escape the police. But she refuses, she'll never abandon her home and her life. Jeffrey is dumbfounded that she could treat him this way after he killed her husband for her! He pulls out a gun, but it's wrestled out of his grip by Gunner, leaping out of hiding. The confession was made in front of a police officer, so both Jeffrey and Bell are taken into custody.
The court finds them guilty of murder, and they both receive life sentences.
