Scientist and explorer George Challenger learns from a dying colleague of a prehistoric world, and organises an expedition to find it.

Desperate to escape and more than a little greedy, Marguerite offers Veronica to a tribal chief in return for jewels and safe passage off the plateau for her group.

The expedition encounters a world where dinosaur descendants rule and men are slaves, good only for eating, working and fighting to the death in a coliseum.

Stung by a giant bee, Summerlee lies near death, and Challenger seeks a way to repel an attack by the ape-men.

A warrior queen will release captive Challenger if his colleagues can recover her husband's bones from the Cave of Fear.

Christecs brand Summerlee (Michael Sinelnikoff) a devil after he revives a drowning child. With Peter McCauley, David Orth, Rachel Blakely, William Snow and Jennifer O'Dell.
