Monster hit Primeval is back for a second series. Evolutionary zoologist Nick Cutter and his team do battle with more savage dinosaurs and other deadly foes, as unexplained anomalies continue to rip through the fabric of time, causing havoc in the present day. Claudia reappears, looking exactly the same, but with no memory of the past, or Nick. It seems he altered the present when he went back in time, but how? And now, bizarre creatures from the future are materializing too.
