The Phantom from 10,000 Leagues (1955)

In the mysterious depths of the Pacific, an enigma lurks beneath the surface, where an ambitious professor conducts clandestine experiments for a coastal oceanography college. When the peaceful routine of the local fishermen is shattered by a string of inexplicable deaths, a government agent, not of the FBI, and an astute scientist are dispatched to unravel the mystery. Their investigation plunges them into a world of atomic intrigue and monstrous terror. The ocean floor is home to an uncharted source of atomic power, guarded by a monstrous entity, twisted and mutated by the radioactive influence. As the body count rises, charred and radioactive, the connection between this deep-sea leviathan and the professor becomes ominously clear. The professor's secretary reveals a chilling secret - her employer's experiments have given birth to this aquatic nightmare. But the shadows of conspiracy run deeper when the agent uncovers negotiations to sell not only the atomic secrets but the terrifying monster to a foreign power. The professor's assistant, a traitor with a thirst for power, murders the secretary, revealing himself as the manipulator behind the impending atomic trade. As the agent apprehends the treacherous assistant and the foreign agent, disaster strikes off the coast with a ship exploding in a ball of fire. The professor, once blind to the consequences of his actions, now sees the monstrous creation and the undersea weapon as a threat to humanity. With a newfound resolve, he embarks on a daring dive into the sea, armed with dynamite and a desperate plan to obliterate the weapon and the monstrous guardian. In a climactic showdown, the professor is seized by the monster, and in an explosive finale, the professor, the monster, and the atomic weapon meet their end, leaving the ocean depths once more in tranquil silence.
