Recap / Primeval S 1 E 3
Cutter realises the anomalies are even more complicated than he thought when a mobile anomaly opens, moving from a swimming pool to a reservoir to a basement. Through it comes a Cretaceous mosasaur, and even more startlingly a message from Helen Cutter. Nick goes through and finds her alive and well, but less than willing to help.
