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.

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 golfer is killed by a huge winged dinosaur and the team argues over whether to kill it or send it back to the past. When Connor and Abby trek into the forest to find Rex, they quickly learn that the winged creature did not come alone.

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.
