Primeval

An apparent dinosaur sighting leads Evolutionary Zoologist Nick Cutter and his team to the Forest of Dean - the very same forest his wife disappeared into years ago. While searching for the mystery beast, they make an even stranger discovery.

When a giant spider attacks on the London Underground, Cutter's team descends into the maze of tunnels to investigate. However, there are more than spiders lurking in the darkness and soon the team comes face to face with an even more ferocious predator.

When an ancient, vicious sea monster is loose in the water system, Cutter realizes the key to stopping it may lie with his long-lost wife. He must travel through time in a desperate attempt to find her and bring her back to the present.

A flock of dodos comes through the anomaly and the docile birds bring a deadly parasite with them. Connor's suspicious friends tail him and steal one of the dodos, but when one of them is bitten, they must find him before he can infect anyone else.

A highly evolved predator from the future is stalking the team and, even worse, breeding. To figure out what caused its arrival the team travels back into the past, but their journey through time causes an unexpected and radical change in the present.
