Water Dwellers"The first episode begins with an illustration of the giant impact hypothesis: approximately 4.4 billion years ago when the Earth was formed, it is conjectured that a planet-like object referred to as Theia collided into the early Earth, dynamically reshaping the Earth and forming the moon. The episode then jumps ahead to the Cambrian Explosion, showing the first diversification of life in the sea. Strange predators called Anomalocaris feed on Trilobites, fight with each other, whereupon the wounded loser is attacked and nibbled on by a school of Haikouichthys.
The Haikouichthys are said to evolve into Cephalaspis, an armored jawless fish which is said to have the first good sense of touch. One Cephalaspis is chased by a Brontoscorpio "giant scorpion" but due to her electric touch sensing ability, she dodges the attack and the Brontoscorpio gets eaten by a Pterygotus, a 3 m long eurypterid hiding in the sea floor. Cameroceras also live in these waters. The film also shows a school of Cephalaspis swimming from the ocean to rivers where they spawn. A group of Brontoscorpio crawl on land and also arrive at the Cephalaspis's spawning pool. The Brontoscorpio feast, but there's too many Cephalaspis for them to eat at once. One Brontoscorpio moults and misses the feast.
Then the show moves on to the Devonian, when Cephalaspis has evolved into Hynerpeton (though it must first pass through the lobe-finned fish stage), amphibian-like tetrapods. Though they can go on land, Hynerpeton have to keep wet, and must return to the water, where sharks like Stethacanthus and a two ton killer fish, Hyneria, can hunt them down. Later a Stethacanthus is eaten by a Hyneria. One male Hynerpeton finds a mate, but just after spawning, he and his mate are ambushed by a Hyneria. They escape to land, but the narrator explains Hyneria has strong fins that can propel herself out of the water. The episode ends with the male Hynerpeton gets eaten by the Hyneria, which has crawled onto land. And right at the end the narrator says that amphibians leave the waters and their eggs change. They have a hard shell which protects the young inside. The First Reptiles Evolved. The spider is about to attack them."

Reptile's Beginnings"The second episode shows the swampy coal forests of the Carboniferous. It explains that because of a much higher oxygen content in the atmosphere, giant land arthropods evolved, such as a "Mesothelae" (a member of the primitive spider suborder), Meganeura, a dragonfly and Arthropleura,a huge millipede relative."

Clash of Titans"The third episode is set in the Late Permian, on the supercontinent Pangaea, which was covered by a vast and inhospitable desert. In this arid climate, early therapsids, which are described as more "mammal-like" than reptile, are shown fighting to survive."

Before the Dinosaurs"Begins in the Cambrian period 530 million years ago, showcasing how a simple jellyfish-like sea creature evolved over 200 million years into new creatures with eyes and protective external and internal skeletal systems. These adaptations resulted in the world's first fish, arthropods, amphibians, and land-loving reptiles and early therapsids, which are described as more "mammal-like" than reptile, are shown fighting to survive."
