Lucas Darius Williams-Watt is a curious 13-year-old who spends a day at his grandmother’s old house, now up for sale. While wandering the dusty shelves, he uncovers a gleaming crystal tucked inside a box and pockets it, drawn by its strange allure. The adventure kicks off aboard a plane when, during a moment of quiet, he places the crystal on the next empty seat and it begins to glow with a quiet, pulsating light. A sudden catastrophe strikes the aircraft, leaving Lucas stranded in a bewildering world where ghost ships drift on the horizon and prehistoric beasts wander the land.
As he searches for signs of life, a distant radio crackle flickers through the static, guiding him deeper into a lush, dangerous jungle. There he encounters a striking young girl, Kate Kate Rasmussen, who insists she is from the 1950s and seems to know far more about Lucas’s glowing prize than she should. She offers him a key artifact of her own—a diary she calls a Survival Guide—and explains that she once owned a similar crystal. Her presence beside him feels oddly reassuring, even as the surroundings feel relentlessly alien.
The jungle world is alive with wonders and dangers. A Sinornithosaurus named Mimos, gifted with the uncanny ability to mimic almost any sound he hears, shadows their steps, providing both company and peril. After a shuddering earthquake, a strange mist swirls through the air and hearing a distant broadcast becomes a lure for Lucas and Kate. The mist seems to travel across time, pulling empty airplanes from different eras into this place, each vessel carrying salvaged goods rather than people. When a fresh plane lands, the pair seize the chance to explore it, only to be seized themselves by a group of tribal people who trap them in a pyramid-shaped wooden cage.
Inside the cage, a fellow prisoner recognizes the crystal in Lucas’s hand and speaks of what it truly is—a “sing sing stone.” He whistles, and the surrounding mist swirls again, hinting that these stones exist in larger clusters somewhere between two looming volcanoes. The prisoner insists that seismic forces give the stones their resonant frequency, creating a portal that could be Lucas’s way back home. Realizing there’s more at stake, Lucas and Kate devise an escape plan. They slip out through a hidden opening atop the cage, and Kate frees a menagerie of enormous pterosaurs. One of these airborne beasts carries them toward the looming twin volcanoes, though the descent is rough and perilous. A Tyrannosaurus rex roars in pursuit, but Mimos answers with a precise roar that unsettles the predator, buying them precious moments. More dromaeosaurs give chase, yet the pair presses on toward a remote cave tucked between the volcanic sentinels.
At the cave’s mouth, Lucas uses a jar of water to coax the right resonance from the crystals. The moment the sound is released, the crystals flare to life and light spills into the air, forming a radiant portal. Yet Kate refuses to retreat without a piece of her past—her diary—that fell into a stone cavity somewhere along their journey. She argues that without proof, no one will believe their incredible tale, and she insists that Lucas step through the portal first, promising to follow. Reluctantly, Lucas enters the shimmering doorway and vanishes from the island, leaving Kate to face whatever fate lies beyond.
A quiet, surreal sequence follows as Lucas awakens in a hospital room. He is greeted by the news of a mysterious island and then by his grandmother Kathryn, who teases that she prefers Kate because, in her own old-fashioned way, she believes Kate would never abandon him. The revelation lands with a thud: the Kate he met on the island appears again in the hospital, and she carries the very diary that proves their voyage. With Kate’s diary in hand, she receives the Nobel Prize for Science, a testament to the extraordinary discoveries they’ve unearthed together. Back on the island, Mimos is seen peacefully riding the back of a sauropod herd’s leader, a serene image that bookends the tale as the screen fades to black.
