The story begins. When evolutionary zoologist, Nick Cutter, sets out with his graduate student Connor Temple and lab technician Stephen Hart to investigate strange animal sightings in the Forest of Dean, he finds himself confronted with the subject of his studies in a way he could never have imagined.
And so begins a journey of discovery in which the team begin to realise that vicious creatures are popping up in the present day through anomalies - rips in time that lead back to the prehistoric era.
There's more than professional intrigue behind Cutter's investigations though; eight years ago his wife disappeared from the heart of the forest.
Along the way, the crew find themselves face to face with 15-foot millipedes, vicious sea creatures called mosasaurs, parasite-carrying dodos and giant pteranodons, while at the same fighting the off the bureaucrats who would like to sweep their findings under the carpet.
There's no chance of that though, especially with Cutter so determined to find out where his wife fits into all this. Unfortunately for him, when the two are finally reunited, things don't turn out quite the way he'd hoped...
