During an anomaly response that appears to be a false alarm, reporter Mick Harper (Ramon Tikaram) steals a handheld detector from Jenny’s car. When is goes off, Mick, his boss, Katherine Kavanagh (Ruth Gemmell) and a camera crew race to the scene where they find the anomaly inside an airport hangar. They are on hand when a baby velociraptor comes through. It quickly returns back into the anomaly. Then a Giganotosaurus comes through and eats the camera crew. It goes back into the anomaly for a time.
Conner (Andrew Lee Potts) is allowed to test out his new device and try to lock the anomaly. Before he can the Giganotosaurus returns and rushes out onto a runway. Danny Quinn (Jason Flemyng) shows up wanting to help.
The building where the original so called false alarm triggered is Christine Johnson’s (Belinda Stewart-Wilson) research center. Christine and her head soldier, Captain Wilder (Alex McSweeney) have a cloaking device that hides the existence of an anomaly to the future. They are trying to find a way to control the future predator. Christine knows that the artifact that Helen Cutter (Juliet Aubrey) had is at ARC and she is looking to find a way to get it.
Abby’s (Hannah Spearritt) brother Jack (Robert Lowe) comes to town.
Episode 4 of season 3 features a baby Velociraptor and a Giganotosaurus. A Giganotosaurus was a theropod dinosaur that lived during the Cretaceous period. It was bigger than Tyrannosaurus Rex but smaller than Spinosaurus. It had three claws on its forelimbs rather than two, and the forelimbs were also bigger compared to its body in comparison to T-Rex’s forearms.
The Cloaking Device, although never seen, was used by Christine Johnson to conceal an Anomaly presence. It was used by Christine to hide the fact that she had an anomaly at her research center that she used to travel back and forth to the future to hunt for the Artifact. How the cloaking device worked is never mentioned.
The Anomaly Locking Mechanism was created by Connor Temple. The device reversed the anomaly’s polarity which locked the anomaly so that nothing could come through or go into an anomaly. It could also be used to unlock anomalies that had been locked. The look and portability of the Locking Mechanism changed and improved as modifications were made.
Connor nicknames the Giganotosaurus “G-Rex”.
