Synopsis for Superman: "Superman Battles Death Underground"
There is a cave-in in the Blakely coal mines, and a miner is trapped. Superman makes his way to the mine, and discovers that the rescue crew has been stopped by poison gas (by which he is unaffected). He rescues them, as well as the trapped miner.
The next day, he asks the miner, Stanislaw Kober, what he thinks caused the mine collapse. Kober says that everyone knew the mine was unsafe, but management did nothing to prevent the collapse. Thornton Blakely, the mine owner, says otherwise, claiming that Kober's own carelessness caused the collapse.
Superman decides to sneak into the Blakely estate dressed as a miner. He finds a party going on and gets captured. Blakely lets him stay at the party because he's coming up with an idea: Superman will lead them all down into the mine, where they will continue their party.
Once they are all in the mine, Superman attacks the tunnel-supports, causing the entire party to be trapped under a cave-in. Blakely remembers the safety devices. He sets them off only to discover that they've rusted over. They attempt to dig their way out, but they soon get winded. Blakely curses himself for treating the miners so badly. With everyone else in the party collapsed, Superman tears down the barriers so that the rescue workers can save everyone. Several days later, Clark Kent once again interviews Thornton Blakely, who now reveals that he is going to start treating his workers better.

Synopsis for Scoop Scanlon: "Murder at the Blue Bird Dance Palace"
The murder of Bat Wilson, a rich socialite, sends Scoop and Rusty out to the Blue Bird Dance Palace, a place Wilson often frequented, to investigate. Once there, Rusty stands by to keep an eye out for suspicious characters, while Scoop plays the part of a young millionaire looking for a good time. Scoop eventually meets a woman who seems very interested in him, or more accurately, interested in the fortune he's claiming to have. Suspecting she may know something about Bat Wilson's death, he invites her for a romantic ride out on the town. Before leaving, Scoop tells Rusty he may have found a lead in the case. Scoop takes the girl to his car, and then she guides him to a spot that she says is good for moon-gazing.
A little after the car comes to a stop, a masked robber approaches them holding a gun. He demands everything Scoop has on him. Quickly, Scoop leaps out of the car, rushing the crook and knocking his gun away. The struggle, but the crook gains the upper-hand and holds Scoop while the woman, who was in working in cahoots, retrieves the gun and points it at his chest. Fortunately, Rusty appears behind her, grabbing her and making her drop the weapon. Scoop delivers a hard punch to the crook, then he grabs the gun and uses it to force them back to Police HQ.
The woman and her partner would lure unsuspecting folk who looked like they were doing well for themselves out to a secluded spot where they'd proceed to rob them. It turns out that Bat Wilson fought back, and they were forced to kill him. Rusty tells Scoop he got enough pictures for the story.

Synopsis for Tex Thomson: "The Sealed City (Part 2 of 3)"
After dining, the Gorrah asks Tex and Bob for their firearms. The men question this demand, but the Gorrah shows them that their guns are useless in the Sealed City by shooting the servant Daroka five times around the heart. While at first he seems dead, Daroka walks away, apparently unfazed by the attack. The Gorrah leads them across a drawbridge to his laboratories to demonstrate how his people are invulnerable to bullets. Crossing the bridge, they are confronted by two giant men. These giants are more of the Gorrah's servants, Scharem and Hawntem, and they will obey his every command. On the Gorrah's orders, Scharem picks up Bob. Tex swings into action and punches Hawntem in the face. Hawntem begins to draw his sword, but the Gorrah orders Scharem to let go of Bob. Backed against the wall, Tex and Bob fall into the Gorrah's trap. He presses a button, sending them through a trapdoor and into an underground river to drown. Fortunately for them, the river is shallow, and the duo swim to safety on a distant shore. They find a man buried up to his neck in the dirt with ants swarming him. They rescue the man, who reveals himself to be the real Gorrah and the other Gorrah to be an imposter. The fake Gorrah is watching their every move and summons his giant servants to finish the job of killing the trio. They spot Scharem and Hawntem first, and Bob acts as a decoy, leading them into an ambush. Tex, Bob, and the real Gorrah make it to the palace and confront the imposter. The Gorrahs fight each other, and the fake Gorrah throws a knife at the real one. Instead of hitting its target, the knife hits a hidden switch, throwing the imposter into a pit. Tex and Bob have helped return the Sealed City back to its rightful ruler.

Synopsis for Chuck Dawson: The 4-G Gang (Part 3 of 14)"
Butch and Trigger have Chuck Dawson at gunpoint. They move in to search him, which is just what Chuck has been waiting for. He moves fast and grabs the gun from Trigger, then delivers a haymaker punch to Butch behind him. He runs off down the alley, climbing up a nearby roof where he won't be seen. Watching from above, Chuck spies the town sheriff put up a poster with his face on it: Wanted For Murder, an obvious frame-up. Now he'll have to clear his name before he can move on out. Looking down on the other side of the roof, Chuck spots Butch lurking around looking for him. He dives on Butch and, after a brief scuffle, Chuck guides him into the barn at gunpoint. Tying up the gun-toting thug with a lasso, Chuck questions him about his horse's whereabouts. Butch responds that his boss had the horse hidden by a creek behind the dance hall. Right when Chuck is about to leave, Butch's partner Trigger enters. Chuck quickly delivers a jab to the jaw before Trigger can fire his pistol. Leaving the two men hog-tied, Chuck exits the barn.
Hearing the approaching sound of footsteps, Chuck climbs up a nearby tree where he overhears two ne'er-do-wells talking. They plan on using Chuck's horse to frame him for a job. Chuck intends to stop them.

The police commissioner and Zatara are discussing a recent string of murders with the same MO: several wealthy men have been killed by assassins piloting airplanes. While at his hotel, Zatara hears of another attack over the radio and sends an astral projection of himself to the scene. He sees his rival the Tigress and decides to follow her. The Tigress enters a law office, revealing that the recently deceased man had included her in his will. She feels Zatara's presence, but the magician quickly leaves. Zatara fills in the police commissioner and volunteers to collect the evidence to take down the Tigress. He takes his servant Tong to the airfield to get flying lessons. Returning to the city, Zatara hires an escort to bring along to various dances around town. At a club, he sees the Tigress who is already seducing another wealthy old man. Zatara confronts this latest target the next day and rescues him from another air attack. The Tigress is exposed in the newspapers, and the Tigress plots to take down Zatara. Zatara sneaks himself and Tong past two thugs outside and makes his way to the airfield. He casts a spell on Tong to help his flying abilities and the two zoom away to the Tigress' hideout. Tong and Zatara engage in a dogfight with two criminals, but Zatara transforms them into an eagle. The duo reach the hideout and take down the thug guarding it.
