Just when the human race believes that it is responsible, Mother Earth sends earthquakes, tidal waves and volcanoes to push civilization back to the dinosaur era. But Jack Tenrec makes a real prize - a classic Cadillac. Jack and beautiful (and dangerous) Hannah Dundee begin their full-color adventures in the future age of the dinosaurs.

In the "archipelago of stone", Ambassador Hanna arrives in the city of Dundee in the sea. Team poachers want her to die, and it's up to Jack Tenrec, to stop them. In the "opportunists" Hannah and Remfro devise a plan to use the city's population of pteranodons. In the "law of the land", Jack has to deal with a poacher.
