Synopsis for Captain Marvel: "Captain Marvel battles the Underground Mystery Menace!"
A new-age prospector rushes to town to stake a rich uranium vein, though something sinister is lurking in the caves once he’s gone. Billy Batson soon reports on the uranium in Crystal Cavern, which the government is very willing to buy off of people, likening it to the Gold Rush. Billy figures out that reporting on the scene might be an interesting idea and flies there by calling SHAZAM to summon Captain Marvel. Captain Marvel starts to break up minor scuffles going on and enters Crystal Cave, hearing the sinister chuckles of Doctor Sivana. He dismisses it at first as a cave noise until someone falls into a crevasse and he’s forced to fly down to catch them and a man being attacked by a Giant Cave Lizard. Captain Marvel realizes he’ll need to stick around to keep this place safe and stops a falling stalactite from crushing a man shoveling handfuls of uranium into a bag. Captain Marvel looks at the walls and finds that this isn’t pitchblende, the ore that uranium is derived from, but quartz with some uranium ore just sprinkled on the ground. He quickly puts together that Dr. Sivana is just salting Crystal Cavern with uranium ore to sow discord and to likely sell the cave for easy money. Sivana manages to shove a bag on to Captain Marvel’s head and escape into the caves, which create so many echoes that it’s hard for even Captain Marvel to find him, but Captain Marvel figures out that this is just because he’s installed a PA system. Sivana announces over the PA that he’s declaring this Sivana’s Underground Kingdom and seals the exits with explosives to trap everyone in his madman’s nation. When Captain Marvel points out he could just make a way out easily, Sivana threatens that he has rigged Sivana’s Underground Kingdom with dynamite and demands that he wants Billy Batson to come forward.
Captain Marvel returns Billy, who heads in and finds Sivana has rigged a rope around a stalactite to knock him out, then drops him bound and gagged into a bottomless-looking pit. Waking up, Billy is attacked by the same Giant Cave Lizard he ran into earlier as it tries to eat him, but he hooks his gag off on one of its teeth and calls SHAZAM to summon Captain Marvel, seemingly destroying the Lizard. He flies up, punching out Sivana and then punches a tunnel to the surface out. However, the prospective prospectors are remaining inside for a good reason; Crystal Cave is filled with tons of actual gold! Billy later signs off saying that Sivana was really the only one swindled altogether.

Synopsis for Golden Arrow: "Outlaws' Upset"
Outlaw "Coyote" Bill and his goon, Luke, are hiding out in Dry Gulch from Golden Arrow in anticipation of robbing the general store. Coyote Bill offers a novel idea on how to fight him: They pick a fight and then take away his bow and arrow. Golden Arrow is soon informed that someone has violently attacked Old Ben Stokely at the Saloon. Golden Arrow sets down his bow and arrows and punches over Bill and Luke nicks them while his back is turned. Golden Arrow reports the theft to the Sheriff, but he points out that lots of people in town would do it, some just for fun, but a rock crashes through their window, a distraction as Bill and Luke dash in and hold them up at gunpoint. Golden Arrow and the Sheriff are pushed into their own jail as the outlaws leave the keys on their desk, far out of reach. They move back to back to untie their bonds and then dislodge a leg off their jail cell cot to fletch into an arrow that Golden Arrow uses to harpoon the keys. They find the goons taking over the general store to hold up the owner, Cal Turner, so Golden Arrow picks up the Sheriff's suspenders and uses it to shoot the carved arrow at Luke, making him drop his gun and freak out, thinking they're free. Golden Arrow manages to overtake them by ambushing them from a tree branch and defeats the two in a quick fistfight and they're soon arrested. Golden Arrow tells the Sheriff that suspenders are good at more than holding up his pants!

Synopsis for Lance O'Casey: "Lance O'Casey and The Great Oil Swindle!"
Lance and Mike notice their old friend Inspector Blake being shoved into a car that nearly drives into them peeling out before crashing into a lamppost. They drag Blake from the car and find him starving and confused due to having been imprisoned by someone for a week. He manages to get down a small dinner and tells them that an oil stock racket is being set up via a mail fraud in the gulf coast. Lance points out that usually oil is a pretty terrestrial resource, but Blake reveals these are a new sort of "offshore" oil rig run by Tideland Oil and their owner, Nick Bilks. Off the coast of Cajun Island, he is setting up another oil field scheme and that he was kidnapped by his goons to keep him out of the way. Lance and Mike decides to help and head out to Bilks' oil field, where the shifty gangsters sure does seem to strike oil respectably and they leave. However, as the Starfish leaves, the goons snicker about having fooled them by faking this discovery. Lance and Mike notice a loaded tanker that seems to be chugging along while still anchored to shore. They decide to look into this by nightfall and take a dinghy to Cajun Island to look into this. Lance finds that Bilks' oil derrick isn't actually attached to anything below the surface and that the tanker is actually carrying all the oil that he can shoot out of the derrick when needed. However, when he surfaces again, he's brained with a wrench by one of Nick's men. Lance wakes up while being tied up and kicks off his captors and fights them off until Mike and Blake arrive and defeat Nick by shoving him off the ship and then dragging him back up. They soon arrest him.

Synopsis for Ibis the Invincible: "Ibis the Invincible and the Magician of Mars!!"
On the Planet Mars, the great magician Liart is weak and says his magic powers are no longer powerful enough to win and the Rust Men will soon invade and kill them all. His apprentice, Geron, tells him not to surrender, but Liart says he must find another champion to save Mars, Prince Ibis of Earth! Dying, Liart sends Geron to Earth and he suddenly shows up in Ibis and Taia’s apartment. He explains that the Rust Men are brutal barbarians are destroying Mars and Prince Ibis recognizes that Liart is clearly a planetary contemporary of his and wishes himself and Princess Taia to Mars to look into things. Arriving at Liart’s castle, they find a bridge lowered over the moat, indicating that the Rust Men have arrived and have already slain Liart. The Ibistick begins to vibrate, a sure sign of evil as Princess Taia notices that the Rust Men are literally made of rust and can turn into a fine powder and his magic caused him to appear now, revealing they look like red four-armed cavemen and it starts strangling him. Geron takes up Liart’s magical sword and fights off the beastly Rust Man. Ibis worries they may be more powerful than he thought and Geron says they destroy all green and growing things, leaving behind only desert. Ibis decides that he must learn their weakness and decides to spy on their camp from along the canals, where the Rust Men refuse to go.
He heads three klicks and finds the Rust Men’s camp and wishes to understand their language. They talk openly about how they’re proud to murder an old man in his bed and now they can conquer as they wish and their weakness being water, which they intend to offset by draining the canals out. Before Ibis can wish for something to defend this, a Rust Man leaps on him from behind and punches him out. He awakens tied to a big rock and they sentence him to death by smothering, turning into a more powdery form to do so. Before he can be, Geron rushes in and Princess Taia frees Ibis as the Rust Men regroup and then scarper. Ibis coldly wishes for a rainstorm that melts the Rust Men, killing them all. Geron buries Liart and Ibis tells him that he would have been proud and that he is now worthy to take on Liart’s mission of defending Mars. Geron says that a new Mars that is no longer covered in rust will prosper now and Ibis goes back home with Taia. Later, they look to Mars and Ibis notes how soon it may be no longer be a red planet, but a green and fertile one like Earth...
