Dangerous Seas
Nigel travels back in time to the seventh deadliest sea of all time, the Ordovician period (450 million years ago), where he is attacked by sea scorpions and comes face-to-face with a giant orthocone. He then explores the sixth deadliest sea, the Triassic (230 million years ago), where he encounters a pair of Nothosaurus, the bizarre sea reptile Tanystropheus and the giant primitive predatory ichthyosaur Cymbospondylus, which Nigel keeps at bay through using a cattle prod. Nigel then dives in the fifth deadliest sea, the Devonian (360 million years ago). In the Devonian, Nigel encounters the strange primitive shark Stethacanthus and the placoderm Bothriolepis and he uses a rounded shark cage to protect himself from the giant predatory placoderm Dunkleosteus.

Into the Jaws of Death
Leaving the Devonian, Nigel travels forward in time to the fourth deadliest sea, the Eocene (36 million years ago), where he encounters the strange elephant-related Arsinoitherium. Diving in the Tethys Sea, Nigel encounters the primitive whale Dorudon and the crew of The Ancient Mariner uses recorded whale sounds to attract the giant predatory primitive whale Basilosaurus. In the third deadliest sea, the Pliocene (4 million years ago), Nigel encounters the strange whale Odobenocetops and dives with a adolescent megalodon shark. He later uses the rounded shark cage to dive with an adult megalodon, the largest shark of all time.

To Hell and Back
After leaving the Pliocene, Nigel explores the second deadliest sea, the Jurassic (155 million years ago). There, he meets the giant filter-feeding fish Leedsichthys and predators such as the shark Hybodus and the marine crocodile Metriorhynchus. The apex predator of the Jurassic sea is the giant pliosaur Liopleurodon, which Nigel keeps away through spraying putrescine at them when they approach him. Nigel then travels to "Hell's aquarium", the Cretaceous (75 million years ago). The sheer number of different predators present, including sharks, giant predatory fish Xiphactinus and giant mosasaurs, makes the Cretaceous the deadliest sea of all time. In addition to predators, Nigel also encounters a variety of other Cretaceous animals, such as the aquatic bird Hesperornis, plesiosaur Elasmosaurus, pterosaur Pteranodon and giant sea turtle Archelon.
