Nick Cutter (played by Douglas Henshall) has all the gravitas of a 45 year old stock boy at a supermarket. His wife, Helen (played by Juliet Aubrey) left him for eight years and let him think she was dead. She also had an affair with his co-worker, Stephen Hart (played by James Murray). In spite of numerous betrayals and blatant lies by Helen to both Nick and Stephen, they are both hopelessly in love with the smirking witch. So they keep falling for all of her traps.
Helen has been stabbing them both in the back by working with Oliver Leek to capture the prehistoric animals that pop through the anamoly and put devices into their skulls to control the creatures. The ARC team meanwhile has missed the boat on just about everything, as they spend most of their time being cute and dealing with their personal lives.
In this season two finale, the Oliver Leek story reaches its end, after Nick outsmarts Leek by spilling coffee on the keyboard of his computer. In the real world, that does absolutely nothing. In Primeval, it short circuits an entire mainframe system, and sets loose the wild animals to kill the humans. It just gets dumber from there.
Perhaps because of low ratings or because they needed to cut a salary, one of the ARC team gets killed off, because the device to close the door to the animal enclosure got damaged when Helen got her foot caught by an animal. Nick of course, smashed the door controls, because he is a really smart scientist and he could not figure out how to open the door.
Why they wanted to help Helen is another mystery that was not answered. After all, she was willing to get numerous people killed, including them. Nick stumbles and falls with the gun he has used to keep Helen as a prisoner, and she runs away. Once again, Helen has played Nick, and this time she cost Stephen his life.
The only good thing about this TV series were the prehistoric creatures.
