Fred Wilson (Charles Grodin), an executive of the Petrox Oil Company, forms an expedition based on infrared imagery which reveals a previously undiscovered Indian Ocean island hidden by a permanent cloud bank. Wilson believes the island has a huge deposit of oil. Jack Prescott (Jeff Bridges), a primate paleontologist who wants to see the island for himself, stows away on the expedition's vessel. Prescott reveals himself when he warns the crew the cloud bank may be caused by an unknown beast. Wilson orders Prescott locked up, claiming that he is really a spy from a rival oil company.

Shortly after the dawn of the new millennium, during construction on the London Underground, workers penetrate an underground cave. A huge dragon emerges from hibernation, incinerating the workers with its flaming breath. The only survivor is a boy, Quinn Abercromby (Ben Thornton), whose mother Karen (Alice Krige) is the construction crew chief; Karen is crushed to death while protecting Quinn as the dragon climbs to the surface. It flies out of the Underground and more dragons appear, multiplying rapidly. Shown in newspaper clippings and a voiceover, scientists discover that dragons are a lost species responsible for the extinction of the dinosaurs by incinerating them and eating their ash, as well as ice ages. The dragons are speculated to hibernate after destroying most of the Earth's creatures until the planet repopulates. After the dragons' awakening humanity resists militarily, including a 2010 use of nuclear weapons; this, however, hastens the destruction and within a few years humans are nearly extinct.

Pompous paleontologist Rick Marshall has a low-level job at the La Brea Tar Pits, three years after a disastrous interview with Matt Lauer of Today became a viral video and ruined his career. Doctoral candidate student Holly Cantrell tells him that his controversial theories combining time warps and paleontology inspired her. She shows him a fossil with an imprint of a cigarette lighter that he recognizes as his own along with a crystal made into a necklace that gives off strong tachyon energy. She convinces him to finish his tachyon amplifier and come help her on a seemingly routine expedition to the cave where Holly found the fossil, which is in the middle of nowhere. With cave gift shop owner Will Stanton they raft into the cave, where Marshall has detected high levels of tachyons. He activates the tachyon amplifier, triggering an earthquake that opens a time warp into which the raft falls. The group finds themselves in a desert, filled with various items from many eras, and without the amplifier. They rescue a primate-like creature, Cha-Ka of the Pakuni tribe, who becomes their friend and guide.
