In a quiet California ranch house, a brilliant but eccentric radio hobbyist named Jason Gridley stumbles upon a strange new wave that seems to carry faint human voices from an unknown realm. Intrigued, he shares his discovery with a seasoned adventurer, who dismisses the chatter as fanciful at first but soon becomes convinced that the signal points to Pellucidar, the legendary world hidden beneath the Earth’s crust. Their conversation sparks a daring experiment that could open a portal to that inner world, promising encounters with prehistoric beasts, savage tribes, and untamed jungles.
The story follows the narrator’s journey alongside the intrepid Tanar, a native of Pellucidar, as they navigate this strange land’s perils and mysteries. From volcanic islands to glittering twin suns, they confront both wonder and danger, while an uneasy alliance with locals tests their loyalties. Listeners will be drawn into a vivid, classic adventure that blends speculative science with the timeless allure of an unknown world.
