Things have changed at the ARC. With Connor and Abby still missing in the Cretaceous, Danny stranded in his search for Helen, the ARC has been rebuilt, with a new building and a new team. This new ultra-efficient operation is thrown into disarray however when the Dracorex escapes from the menagerie, forcing them to mount a massive recovery operation.

Meanwhile, after narrowly escaping an angry Spinosaurus, Connor and Abby’s luck seems to improve when they find Helen’s anomaly device buried in a raptor’s bower bird-like nest. They use the device to open an anomaly but before they can get through the Spinosaurus returns. Connor and Abby have to use all their wits to out-manoeuvre the beast but they eventually make it through. To their relief the anomaly has brought them ‘home’, into the waiting arms of a bemused Matt and a joyous Becker. That is, until Connor’s showing off manages to reopen the anomaly and let the Spinosaurus through!

Becker, along with new field leader Matt, attempt to corral the creature back through the anomaly during a high octane chase, ending in a dramatic stand off inside a massive indoor arena. Connor inadvertently saves the day as he drops Helen’s device into the creature’s open mouth, triggering an anomaly. The creature implodes from within.

But on returning to the ARC, new boss Philip informs Connor and Abby that they are no longer needed. They’ve been away too long. Will things ever be the same again?

Meanwhile, Matt is meeting a mysterious stranger, who seems to know all about the ARC operation – is there more to Matt than meets the eye?
