Synopsis for Captain Marvel: "Captain Marvel Battles the Amazing Island Thief!"
A freighter, the SS Pacific is heading out to the Twin Islands, but are very worried that there’s only one of them! News soon spreads to WHIZ-TV and Billy Batson reports on how almost a dozen small uninhabited South Seas islands have just gone missing! Once finished, he decides to get Captain Marvel involved by calling SHAZAM! The World’s Mightiest Mortal flies off to the Twin Islands, finding both of them are gone now and, what’s more, they’ve been ripped out from their foundations underwater! He soon spots the two drifting islands threatening to crash into the Pacific and lifts it out of the way, but wonders how this has been done.
Elsewhere in the Pacific, World’s Maddest Scientist Dr. Sivana is using a Gravity Ray Machine to do so, dragging more and more islands to himself, stealing islands and planning to steal an inhabited island next, the population of Bongdok Island, but when he does so, Captain Marvel gets involved by following where the Island Thief is thieving these islands too, which turns out to be into a typhoon. He soon finds through it in the “middle” of the Pacific Ocean is an artificial archipelago. Sivana, spotting him coming, dives in his spherical bathysphere and tells him that he will surrender or he’ll sink Bongdok Island. Captain Marvel agrees, entering the bathysphere’s airlock and calling SHAZAM to return Billy. Sivana pitches a wrench at his head and Billy wakes up bound and gagged on the floor once more. Sivana reveals his big plan is to steal every island to create a gigantic “Sivana Continent” in Polynesia and anyone who fights back will be sank into the ocean. Sivana proceeds to roll Billy back into the airlock to let him drown, but when the water rushes in, Billy manages to slip his gag and call SHAZAM. Captain Marvel easily punches through the pressurized wall and punches out Siavana before he can activate his island-sinking machine, letting the whole machine flood with water, destroying it, then takes Sivana to prison. Billy signs off later saying that Captain Marvel pushed the islands back into place and many engineers “anchored” them in place again, but notes that Sivana is still on an island… called Alcatraz!

Synopsis for Golden Arrow: "Golden Arrow Fights Locusts and Landgrabbers!"
The Sheriff tells Golden Arrow that there's a big ranchers' meeting at the Town Hall and heads in to hear from John Davy, a man buying up land lately and is offering to do so to buy up the three areas of the nearby valley. The cowhands refuse, since it's good land for them, but John Davy just openly threatens them in public. Suddenly, a man runs in to say that locusts have invaded from the mountains and Golden Arrow orders the men to start up some oil-bearing smudge fires to keep the locusts away and runs off to do so. Meanwhile, John Davy orders two outlaws, Tom and Boze, to make sure that the smudge pots fail. Heading back with the three men, Golden Arrow finds the oil has all been dumped out and replaced with water, so they split up to find where the oil's been and find it in a nearby pond. The locusts approach and Tom and Boze ride in to gun down Golden Arrow and the ranchers, but he hides out behind some rocks, fires an arrow to start a brush fire that wards off the locusts. He soon rides back to town, punches out Tom and Boze, then John Davy for hiring them. Later, the farmers thank him for their help.

Synopsis for Lance O'Casey: "Lance O'Casey and the White Panther!"
Lance and Mike are helping an explorer friend Frazer by transporting him and his wild animal cargo to East Africa on a freighter, mostly to repair the Starfish. They find the animals are already caged and ready to transport to Suez and then beyond that to America. Later, Frazer catches the ship's Captain, Hook jabbing a rare white panther in its cage with a stick and admonishes him, since it's priceless in America. Capt. Hook ignores his offer and then conspires with his evil 1st Mate, Spider, on how he'll just steal the cargo and sell it for themselves. Once on the open sea, Spider knocks out Lance and Mike with a club and drags them to the brig with his 2nd Mate, Spike.
Capt. Hook and his men continue to abuse the animals for their own sick amusement. That night, a storm blows in and, with all hands on deck, Lance kicks open the door to find that the waves can broken open the cages and there's now a live tiger on board that they have poked with a stick all day. The rest of the men jump ship and Lance and Mike find Capt. Hook and 1st Mate Spider barely alive in the water and abandon ship when it strikes a huge rock. They soon make it to land and go into the jungles nearby to gather supplies. Hook and Spider get up and ditch them so they can keep the limited food supply to themselves. Lance and Mike soon collect all the food they can on the mildly plentiful island and discover that the white panther has escaped too. They decide they must capture it to get paid eventually and fashion a cage out of bamboo and a grass dummy that jangles around within. The panther tries to eat the dummy and is caught in the cage, they fashion a raft out of driftwood and vines. Hook and Spider plan on stealing the raft, but Lance and Mike wait in the night next to the fire and defeat them in a quick fistfight. Capt. Hook pulls his gun on them and Lance tries to warn him not to stand too close to the panther cage, but Capt. Hook refuses to listen, thinking he's trying to pull something and the panther claws his arm, making him drop the gun. Later, they've constructed a second cage for Hook and Spider, since they don't want to upset the panther by putting them in with him!

- Billy Batson implies that Dr. Sivana is being sent to Alcatraz Federal Penitentiary, which used to be housed on Alcatraz Island, which closed down due to heavy operation costs and extreme salt water erosion in 1963.
- Bongdok Island seems to be located somewhere near Kiribati or Bora-Bora, according to Sivana's maps.
