Determined to prove the existence of The Lost World, dashing adventurer and scholar Professor Edward Challenger mounts a British expedition team consisting of a mismatched group of enthusiasts, all with less than selfless reasons for making the journey. Traveling through the uncharted Amazon jungle to this prehistoric plateau, the group encounters incredible adventures: tribal headhunters, vicious ape men, giant crocodiles, and terrifying dinosaurs!
A band of adventures sets off to prove the existence of dinosaurs deep in the forest of the Amazon. After an unfortunate accident leaves them stranded, they must put their trust in a jungle girl to save them from the dangerous predators on the plateau.
Marguerite makes a deal with a local chieftain to get off the Plateau. The deal is to hand over Veronica to the chief for marriage, something she wants no part of. Like all such schemes, things don't work out as planned and the team must fight a variety of threats in order to save the chiefs daughter, Veronica's virtue, and their own necks.
Roxton is looking for the materials for a crossbow to bag a T-Rex, but when one actually interrupts him in his labors, he runs in the direction opposite his fellow travelers to keep them safe. He winds up falling into a hole that suddenly opens up. When the rest of the group search for him, they also fall into the hole, which turns out to be a whirlpool. It sucks them all under the water, and they emerge in a lake. They quickly find out that in this part of the plateau, the dominant species are lizard-like men, descendants of dinosaurs, and the humans are subservient to them. There is an ancient Roman structure to this civilization, including gladiator-type battles. While Marguerite and Veronica are forced to change into silky gowns for the entertainment of Tribune, the lizard-people's leader, Roxton is chosen to fight another human prisoner. The slaves and travelers rebel, and overthrow the lizard-men's intolerable rule, but not without loss ~ Roxton's opponent's sister ~ a rebel leader.
Veronica and Summerlee are out gathering fruit and floral specimens when they are attacked by a huge bee, one the size of a man. Summerlee is stung, and it leaves him near death.

Summerlee is delirious with fever, and imagines Marguerite is his long-dead wife. She plays along, to sooth him.

Challenger, Malone and Veronica are searching for sulfur, in order to make more gunpowder, when they walk into a burial ground. They are attacked by warriors in black and white paint who capture Challenger. That night the group sneaks into the warriors' village...to find Challenger sitting quietly and drinking tea with a beautiful blonde woman named Cassandra. She and her husband had been part of an early expedition, also stranded and found by the warriors tribe twelve years ago; they were soon made king and queen there. She tells our group that going onto the burial grounds was considered taboo, and for this Challenger would have to remain captive for life. The only way they can save him is by going to the Cave of Fear and retrieving her husband's bones for burial. They set off, but soon discover why the cave is avoided ~ it's walls are covered in a hallucinogenic fungus, with a really nasty additional effect. It drives those affected to suicide - which Cassandra apparently knew when
In this episode, Challenger, Summerlee and Veronica save a little girl from drowning and Summerlee has to give her mouth to mouth resuscitation. Tolmac, of the Christec people, brands Summerlee a witch for bringing the girl "back to life". The Christecs have mingled the Catholic and Aztec religions, with a touch of Conquistador Inquisition, to form their theocracy. Veronica gets away to summon help from the others, but Challenger has to act as Summerlee's lawyer ~ if found guilty, both men will be burned at the stake.
While wandering the plateau, Roxton is attacked by a young man, who bites him during the struggle. Roxton's infected with a disease whose symptoms are slightly bizarre ~ intense craving for blood, pain when exposed to sunlight, a powerful feeling of kinship with nature and "creatures of the night" - he is as a vampire. He runs mad and into the gothic mansion of Calista, a beautiful woman with the same disease. Back at the treehouse, a young native man, Niko, comes forward, declaring his love for Veronica. He and Malone argue and decide to fight to the death for her; she is not pleased! Outside the treehouse, Malone and Niko do start to fight, but quickly stop when Veronica tells them she will kill herself to stop them, and has a knife at her stomach to prove it.
Roxton, Marguerite and Malone are mapping a series of caves, trying to find one that leads off the plateau without much luck. Marguerite, all the while, has been gathering gleaming gemstones in her backpack. At least she will not go back empty handed. A fog begins to fill the air around them...dense...deep fog. From out of the mist forms take shape: cloaked figures and eerie rock formations, encircling a stone slab. They find themselves surrounded by Druid-like figures who swarm over Marguerite. Roxton tries desperately to protect her, but she is torn from his grasp.
The aged guide who brought Veronica's parents to the Lost World dies in Challenger and Veronica's arms, humming "Ode to Joy", leading the explorers to seek out a hidden paradise, where Veronica suspects her parents might be.
While out in the jungle, Malone is hit in the neck with a poisoned dart and dies. A shaman, Lento, heals him and Malone is brought back to life, but Lento has been driven mad. He is sentenced to die by his village, but Malone rescues him. Summerlee is kept captive and will die unless Malone, Roxton and Challenger can bring Lento back. Lento leads them a merry chase, having booby-trapped the jungle, but the men do eventually catch up to him , and he is killed. In the meantime, back at the treehouse, Veronica and Marguerite have had a huge fight, and wind up down an old well, with a hungry dinosaur waiting for them above and snakes, water and each other, in the hole!
Tracking a stream, Challenger, Veronica, Malone and Marguerite run into a group of Vantu headhunters. There is nowhere to run or hide, except in what looks like an overgrown cave opening. They dash into it only to discover it is man-made, an old, crumbling mine shaft. There's a loud rumbling that leads to a cave-in. Veronica escapes, but the others are trapped inside. Near death from suffocation, they are saved by Garza, part of a group banished to the mine by a plague-like disease, and led by a blind little boy known as The Oracle. The boy decrees our group must remain underground forever, and is unswayed even by Challenger's discovery that the tremors are caused by a sleeping volcano waking up around them. On the outside, Veronica manages to get Roxton and Summerlee from the treehouse, but they meet up with the Vantu again, who are not easily persuaded to let them rescue the others from their mountain prison.
Roxton saves Tayra of the Tinta people from a Hikari warrior who is chasing her. The two men fight and the Hikari man is killed. Roxton discovers that the Tintas live in fear of the fierce Hikari, and pay them a tribute to ensure the Hikari leave them in peace and protect them from other dangers. The Tinta are very peaceful, a fishing and gathering tribe, and do not know how to fight, but are determined to stop the tribute practice, but freedom may come at a high price. Roxton and Veronica teach them some fundamentals of hand to hand, help set up some traps to slow the Hikari down and help the Tinta organize in defense of their village, which the Hikari are due to strike, since there was no tribute paid. Challenger reluctantly helps, since he is not sure whether the Tinta are going to survive the fight ~ he does rouse them the night before with some inspring words from Shakespeare.
