ADVENTURES OF CAPTAIN MARVEL

During an archaeological expedition to find the secret of the Scorpion Kingdom in Siam's volcanic Valley of the Tombs, a device of great power, the Golden Scorpion, is discovered hidden inside a sealed crypt. While examining it, the device's quartz lenses are aligned, and a powerful energy beam is released, causing an explosion that reseals the crypt. This allows young radio broadcaster and expedition member Billy Batson, who obeyed the warning on the crypt's seal not to enter, to be chosen by the ancient wizard Shazam. The wizard grants Billy the powers of Captain Marvel whenever he repeats the wizard's name. Captain Marvel's powers can be used only to protect those in danger from the curse of the Golden Scorpion. After the crypt's entrance is quickly cleared, Captain Marvel utters "Shazam!" and returns to his previous alter ego, Billy Batson.

The Golden Scorpion's lenses are divided among the scientists of the Malcolm Archaeological Expedition so that its power can only be used by an agreement of the entire group. When the scientists return to the U.S., an all-black-garbed-and-hooded criminal mastermind, called the Scorpion, steals the ancient device and sets about stealing the distributed power lenses. Several expedition members are killed in the Scorpion's quest, despite Captain Marvel's frequent efforts to thwart his plan. Deducing that the Scorpion always seems to know what happens during the scientists' meetings, Billy later confides to his friends, Betty Wallace and Whitey Murphy, his suspicion that the Scorpion may be one of the Malcolm archaeological team.

Discovering that one of the Golden Scorpion's power lenses was purposely left behind, cleverly hidden in the very crypt where it was first discovered, Billy Batson and the surviving scientists agree it must be retrieved. They return by cargo ship to Siam, where, near landfall, they barely survive a typhoon before finally being rescued by Captain Marvel. They eventually retrieve the hidden lens, but it is stolen by the Scorpion. By accident, from a distance, the Scorpion observes Captain Marvel transforming back into Billy Batson. Capturing Billy and gagging him, the Scorpion interrogates him about his secret. Billy's tape gag is removed when he agrees to talk. "Shazam"! is his only response, and he transforms in a flash of light and smoke into Captain Marvel. The Scorpion's identity is revealed to be one of the last surviving scientists. He is killed by a Siamese native who aligns the power lenses and turns the device's ray on him, vaporizing him.

Captain Marvel tosses the Golden Scorpion and its lenses into a volcano's molten lava to prevent them from ever being used for evil. Upon its destruction, Captain Marvel is instantly transformed back into Billy Batson forever, the danger from the device's curse having now been eliminated.

Captain Marvel defeats the Scorpion, whose identity is revealed as one of the scientists, and destroys the Golden Scorpion in a volcano, eliminating its curse. Billy Batson loses his powers as Captain Marvel is no longer needed.

By destroying the Golden Scorpion artifact, the serial resolves its central conflict and neutralizes the deadly threat, underscoring the theme that unchecked power is too dangerous to exist. Captain Marvel's final transformation back into Billy Batson signifies the end of his extraordinary responsibility, bringing closure to both the personal and supernatural arcs.
