Helen attempts to stop the destruction of the Earth by traveling back in time to prevent humans from evolving. The team decides to chase Helen but must split up when another anomaly appears.

The team try to deal with a group of rhinoceros-type beasts from the Eocene. Danny shows up with a woman from the future who tries to help.

Cutter and the rest of the team are still trying to come to terms with Stephen’s death. A creature that looks like an Egyptian god comes through an anomaly that opens in the British Museum. Egyptologist Sarah Page and new head of Security Captain Becker attempt to find where the creature has gone.

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 Pristichampsus, a kind of monstrous crocodile that can run on two legs. This creature, which comes from a past much more distant than the Egypt of the Pharaohs, somehow became worshipped as a god in that civilization, and is now portrayed in the hieroglyphics on the Sun Cage.

The murderous creature wreaks havoc in the museum before escaping into the city. Helped by Sarah Page (Laila Rouass) the smart and sexy archaeologist at the museum, Cutter (Douglas Henshall) Abby (Hannah Spearritt), Connor (Andrew-Lee Potts) and their new Head of Security, Captain Becker (Ben Mansfield) must track it down before it claims any more victims.

A race against time ensues as the trio track the monster across central London, from the busy banks of the Thames, to the Southbank and Royal Festival Hall. Back at the British Museum, Connor and Sarah guard the Sun Cage and repeatedly attempt to prevent other creatures from bursting through. During their battle, Connor inadvertently ‘locks’ the anomaly shut. Unclear how or why this amazing development occurs he nonetheless feels the beginnings of an idea. He also begins to believe in the legendary curse attached to the Sun Cage and convinces himself he is next in line for the crocodile God’s revenge.

While the team are tangled up with the rather tetchy living legend, Lester has his own troubles when he is summoned to Whitehall by Christine Johnson. Described by Lester himself as a ‘velociraptor, only better dressed. Johnson displays a rather unhealthy interest in the work of the ARC. The meeting is interrupted by the arrival of a solider wanting to speak with her. Distracted she ushers Lester away and engages in a furious conversation with the military man. He shows her a photo of an ancient artefact and apologises for his failed mission to retrieve it telling her that he and his team were attacked by predators.

Can the team safely deposit the creature back into the past, where it can retain its place in Egyptian mythology without Ammut claiming anymore victims? Who is Johnson and what is her interest in the activities of the team? And just what will Cutter do with Sarah Page? She’s seen and heard too much to be dismissed by a Jenny Lewis (Lucy Brown) press release.

The aftermath of the temporal anomalies leaves Nick and Helen retaining their memories of the present, but for his friend, the world, and they, have been drastically changed. Claudia is nowhere to be seen, yet in her place is a very familiar, yet completely different addition to the team.

As Raptors begin to penetrate our world again, attacking a shopping mall, the team unite to face their current problems.

Helen Cutter uses the opening of a new anomaly to escape from custody at the Home Office, leaving in her wake a flock of dodos.
Tom and Duncan steal one of the birds, unaware that they carry a deadly parasite, and when Tom is bitten and begins to feel the urge to attack people, he seeks out Abby for answers.
As Abby desperately tries to evade Tom’s lethal bite, the others try to track him down before a pandemic is unleashed.

In the course of investigating a mysterious animal sighting, Professor Nick Cutter comes face-to-face with a gigantic creature he believed to have been extinct for 200 million years.

But as he and his team struggle to find out where it has come from, a deadly predator goes on the rampage in the local school.
