The Lost World

A fearsome battle has erupted between Drakul and the betrayed Tribune. In an attempt to avoid being trapped in their crosshairs, the adventurers try to cross a bridge spanning a deep gorge, but a bomb sends Summerlee into the depths below. Marguerite and Veronica mount a search to track down and save their friend. Tribune has rescued Roxton from death, but he demands a favor in kind.

While on expedition for a route off the plateau, Roxton, Malone, and Challenger encounter an Amazon woman defending herself from an attacking Deinonychus. After the men come to her aide, Challenger suffers serious wounds. When the woman and her cohort invite the men to their village so his wounds can be tended, they receive a warm welcome.

Challenger builds a windmill. But when his generator is struck by lightning, a portal is opened that ushers in a helicopter carrying a family of tourists from the year 2000. Marguerite attempts her own escape.

While on a research expedition, Roxton is startled by a terrified young woman garbed in opulent evening wear. The woman passes away, and the mystery of her appearance leads Roxton, Marguerite, and Malone to a strange castle, where an ominous rainstorm drives them inside. Inside the gothic mansion, a strange spirit takes hold of the three adventurers, entangling them in a strange love triangle.

A horse without a rider seems to intentionally find and approach the explorers. Roxton takes the mount, but the horse leads and carries him to a mountain tribe that welcomes him as king. Despite Roxton's refusals, the tribes folk and their powerful advisor, Balar, insist that Roxton take the throne, or be killed as an imposter.

The suspicions of the group are stirred when Marguerite suddenly starts acting uncharacteristically kind. Meanwhile, a bizarrely sluggish dinosaur in the jungle likewise rouses the curiosities of Roxton and Veronica. An alien invader is discovered trying to control the dinosaur's body, shedding light on the mystery of Marguerite's behavior.

The explorers discover a map revealing a way off the plateau and out of the Lost World. The group makes their preparations to leave, packing whatever evidence of their findings they can, but Veronica knows she must stay to continue her search for her parents. Despite Nelson's uncertainties about going back, they follow the route outlined in the ancient map and emerge on an ocean coast.

Veronica meets a mysterious shape-shifter in the guise of an old women, who tells her that her parents are alive and safe in a place called El Dorado. After giving her directions to find them, she tells her that she can tell no one and never return. But when Veronica unwittingly releases a savage giant from captivity, the others must subdue hime once again.

Tribune seeks refuge at the explorers' treehouse from Empress Centuria and her legion of Lizardmen. The reptilian soldiers track him down at their haven and take him prisoner, along with Malone, Marguerite, and Roxton. The captives are taken to Centuria's city, where Roxton and Tribune are sent to the Gladiators' Arena.

The Lost World and its inhabitants are plagued by a severe drought. When a pack of hungry, thirsty raptors attack the explorers, a beautiful young woman named Ana comes to their aid. She hopes that, in return, they will escort her back to her pueblo. Ana falls weak, however, and confesses that she and her ancient colony had discovered the Fountain of Youth and her supply is now diminishing.

Veronica becomes the target of trophy hunters after she rescues a Troglodyte child from their gunfire. Veronica rushes back to the treehouse to warn the others, but one of the hunters claims that their party had been commissioned to locate Challenger and escort him back to England. The hunters set up camp near the treehouse, but their story dissolves when they capture Veronica and take her away.

A mysterious drumbeat echoes through the forest as a beautiful stranger begins to follow Roxton. The woman, Danielle, and her village were victims of a Trog attack, and she seeks refuge at the treehouse. Though she has charmed the male explorers, Marguerite and Victoria remain suspicious of her.

While gathering herbs, Challenger inadvertently falls into a trap set by young hunters. The child-hunters take Challenger to their village, a hidden camp populated by orphans. Veronica and Marguerite track Challenger and his captors to their village, where they discover that its orphans are protected by a carnivorous plant that emits poisonous gases.

A strange but handsome visitor named Alex arrives at the treehouse, seeking Challenger's assistance in finding the source of the Amazon. Alex impresses Challenger with his Oxford credentials and charms Marguerite and Victoria. But while sparks fly between the women, Alex seems most interested in Challenger's electrostatic accumulator, a device that becomes targeted by outsiders.

Roxton and Marguerite discover a fissure that they hope may offer a way through the mountains and off the plateau. But when they enter the crevice, the path leads them to a blinding light and an entirely new corner of the Lost World. On the other side of the mountain lies a mysterious reflection of sunlight and an English-style town.

While exploring the jungle, some of the explorers encounter distressed strangers that bear a resemblance to Veronica and Malone. When the strangers' pursuers track them down, Veronica and Malone are taken captive by these mysterious entities with powerful weapons. At the order of their alien leader, Malone and Veronica are taken to a labor camp where they are forced to work for alien overlords.

After the treehouse is raided by a monkey, Roxton and Marguerite track the culprit to a cave. There, they discover a strange amulet that marks them with a tattoo of a dinosaur skull. This imprint seems to provoke some primal instincts from the explorers as they morph into their more beast-like selves. Overcome by a power that science can't explain, the group begins to exhibit heightened senses.

Marguerite and Challenger enter an ancient Temple laden with traps and mystical protections. After Marguerite falls into a pit of spikes, Challenger must leave her to get help. With her injuries come vivid hallucinations, and the carved warriors that guard the Temple come to life. These guardians attack the others when they arrive to rescue Marguerite.

At the brink of an intimate moment, a seismic shift sends Marguerite and Roxton to the bottom of a pit. There, they discover that a pirate from a bygone era left behind his bones and his treasure. The booty instantly attracts Marguerite, and not even warnings of a curse deter her from taking the newly discovered fortune back to the treehouse.

After Malone is attacked by a beast, he and Veronica meet her old friend Danu, who has also been injured. That night, Danu goes missing, and the group travels to his village only to learn that he is a werewolf.

A tumultuous thunderstorm brings with it a haunting vision of the explorers' old companion, Summerlee. Malone sets out after the ghost of the friend they saw disappear into a waterfall. Challenger, Roxton, and Marguerite follow close behind until they are ambushed by cannibals with an appetite for Marguerite.

The incredible occurs when a Navy airship flies over the plateau. Malone manages to climb aboard, but is ambushed once inside. The deceptive Captain Askwith wins over the others with the possibility of flying off the plateau.
