It then cuts to a monologue recapping the events of the past, narrated by Nick Cutter:
My name is Professor Nick Cutter. Eight years ago, my wife, Helen, disappeared. I discovered she had stepped into the past through ruptures in time called 'anomalies'. Now, creatures from the past threaten the future of the human race. There's only a small group of people who know the truth: my research team- Stephen Hart, Connor Temple and Abby Maitland- and government officials James Lester and Claudia Brown. I return from the past to find that something has gone terribly wrong, and Claudia Brown has vanished as though she was never even born. I've come back to a different world, and Helen and I are the only two people who know it...
It then picks up straight from the end of Episode 6. As Nick takes in the information that Claudia Brown has never existed and that the world has changed, the anomaly begins to close. He desperately runs towards the anomaly, but Connor and Stephen hold him back as the anomaly finally closes. Lester begins to leave the scene. As a confused Nick tries to take in what's happened, he learns more about the world he has come back to: no-one has heard of Claudia Brown, and her task of running the anomaly project has been tasked to Oliver Leek, and that the team no longer work at the Home Office, but a facility called the ARC, or Anomaly Research Centre. These revelations cause Cutter to collapse, but Lester and the others dismiss it as stress and amnesia.
Cutter arrives at the ARC (Anomaly Research Centre) and is introduced to Claudia Brown's replacement- Oliver Leek- who acts as though he has known Cutter for a long period of time. Pretending to be recovered, he acts as though he remembers Leek, but in private, confides in Connor Temple that he can't remember a thing. Cutter asks Connor whether he believes that the evolutionary timeline has changed. Connor says he'll accept Cutter's story, but then asks if he has changed: Cutter worryingly replies that some things never change. The timeline change which deleted Claudia Brown has also created a new branch of Nick's organization, with several new staff.
Meanwhile two security guards at the Castle Cross Shopping Centre are attacked and killed by a pair of Raptors. The first attack takes place behind the bowling alley. As the guard's colleague attempts to escape, the second one attacks and kills him. Reports of this get back to the team who are sent to try to capture the raptors that are on the loose.
They discover the raptors came through an anomaly which is hidden behind the bowling alley. Stephen claims that they need better weapons as the raptors are extremely dangerous, but Cutter argues against it, saying that the disruption caused by their meddling with the past has already cost him a close friend: he doesn't intend for it to happen again. During the search they find a cleaner and Connor and Abby are left with the job of taking him to safety. In a locker room, as Connor looks around with the gun, the cleaner is attacked by a baby raptor, which slashes him in the neck, badly injuring him. Connor sedates the baby, accidentally tranquilising Abby in the process, while Nick and Stephen encounter the infant's mother in the bowling alley. Stephen is put in mortal danger by the raptor but when Cutter tries to shoot it, the gun jams. Though the raptor is driven off, Stephen accuses Cutter of allowing the raptor to kill him in revenge for what happened between Helen and him. Nick tells Stephen that he resents Stephen for his affair with Helen, but that if he wanted Stephen dead, Nick would have killed him personally. The adult raptor attacks again, but this time, they are able to tranquilise it.
Connor finds them and alerts them to the presence of the infant. He also notices that the cleaner is gone, although the man was badly wounded. Nick thinks he simply recovered and got out. They theorise that there are three raptors in the shopping centre: having already captured a female and a baby, the chances are the raptors are a family unit. The team tether the young raptor and let it wake, hoping that its cries will attract one of the adult raptors which is still loose. Indeed, another adult raptor arrives, but it cannibalises the infant.
Nick and Stephen are about to sedate the male when Abby wakes up and distracts it. After a chase involving Nick Cutter and Stephen Hart riding on two motorcycles taken from two boys that were riding around the carpark, they finally tranquilise the last raptor. By this point, Lester and Oliver Leek, under the prompting of their Government superiors, decide it would be a good idea to get a PR (Public Relations) liaison to explain the carnage and the aftermath of the anomalies.
At the anomaly, Cutter asks Abby whether she believes the timeline has changed. Abby says she wants to believe Cutter and seems interested in who Claudia Brown was. With no further answers to his current problems, Nick takes the remaining dinosaurs, tied to trolleys, through the anomaly into dry desert hills of the Cretaceous.
Nick begins to walk away, but then a voice behind him calls out. It is revealed Stephen followed him through the anomaly, believing Cutter would try and stay behind. Cutter argues all he wants to do is restore the time-line and bring Claudia back, but he is persuaded to go back to the present by Stephen, as he could change lots of things and still not get Claudia back or even wipe out mankind. By now the drugs have worn off and the raptors wake up and chase them; Nick escapes unscathed, but a raptor grabs Stephen by the foot and tries to drag him back. Nick manages to drag Stephen back just before the anomaly closes, decapitating the Deinonychus and leaving Stephen and Nick in the modern world along with its head.
Later a cover story is released to tell the public is that the raptor was really just a robot model being tested. Suddenly, Claudia Brown returns under a new name, Jenny Lewis, as Lester's new PR woman.
