Monster hit Primeval roars back onto the screens for an extended third season. Still reeling from Stephen's death and with the depth of Helen's betrayal now revealed, Nick Cutter must fight to re-focus his embattled team. Cutter's crew are joined by some new recruits in the form of maverick policeman Danny Quinn, spunky Egyptologist Sarah Page, and the new leader of the ARC's security forces Captain Becker. Prepare for more explosive action as Primeval bares its newly sharpened teeth.
When an exhibition of ancient Egyptian relics comes to the British Museum, an anomaly opens in a mysterious monument called the Sun Cage. A creature emerges from it - a kind of monstrous crocodile that can run on two legs. The team is joined by the ARC's new Head of Security, Captain Becker, and an archaeologist from the Museum, Sarah Page. The race is on to track the creature down before it hits the streets of London.
Cutter's research leads to a prediction about where the next anomaly will appear. They wait to see if an anomaly will appear, but get more than they bargained for when they discover a camouflage beast from the future is living in the house. They also have to deal with a cop, Danny Quinn, who takes an instant dislike to them. The team faces one of their hardest missions yet - how do you catch a creature you cannot even see?
Some cute but surprisingly dangerous burrowing creatures called Diictodons nearly cause a disaster at a hospital when an anomaly opens from the Permian era. Calamity is averted by the team, which manages to get the creatures back to their own time whilst simultaneously delivering a (human) baby. Meanwhile, Helen and her army of 'Cleaner Replicas' attack the ARC.
The largest anomaly the team has yet encountered opens at an airport and a Giganotosaurus comes through. Affectionately (or not) known as a G-Rex, it's like a T-Rex but bigger, meaner and more dangerous. The team has their work cut out as they try to rescue a crew trapped in a 747 and get this mighty predator back through the anomaly. They are helped by Danny Quinn, who turns up unexpectedly and refuses to leave the scene.
The team faces one of its most unusual and dangerous of threats - a deadly flesh-eating fungus. The fungus literally takes over any human who comes into contact with it, turning the unfortunate victim into a hideous shell of their former self, intent only on spreading the fungus further. Can the team find a way to stop it before it's too late?
The team is investigating a mysterious artefact when the ARC is invaded by a Government official backed by the military, in search of it. Taking refuge in a mysterious old hut in some woods, the team finds itself besieged by birds from the Pliocene era when an anomaly opens nearby. Phorusrhacids may look like armoured ostriches in shape, but they are infinitely more dangerous.
When a medieval knight comes through an anomaly chasing what he believes to be a dragon, the team don't just have another dinosaur on the loose, but also a knight intent on slaying it!
When an anomaly opens at a race-car test-track, the team must draw on all its skills to capture and return a lethal, giant carnivorous insect from the future. Things become even more complicated when Abby's brother Jack inadvertently goes through an anomaly to escape the Megopteran. The team sets out on a rescue mission and find themselves in a future world filled with terrifying predators. Can they save Jack and get back alive?
A herd of Embolotherium comes through an anomaly at an off-road motor course. The team arrives, but these seven-tonne rhinoceros-type beasts from the Eocene era do not budge easily. The pressure is on to lure the lumbering creatures back through the anomaly without causing a stampede or being crushed in the process. Danny finally arrives, with Eve, a mysterious woman from the future. To be continued...
When the anomaly at Johnson's headquarters reopens, Sarah and Becker head off to check it out. Helen decides the only way to stop the destruction of life on Earth is to stop humans ever evolving and goes back in time to kill Hominids, the very first humans. The rest of the team must stop Helen at all costs. They endure a harrowing journey back through time via several anomalies, battling future predators, raptors and pterasaurs along the way. One of the team also has a life-changing encounter with the earliest humans, Hominids.
