Primeval

When an exhibition of ancient Egyptian relics comes to the British Museum, an anomaly opens in a mysterious monument called the Sun Cage and a creature emerges from it. The team is joined by the ARC's new Head of Security, Captain Becker, and an archaeologist from the Museum, Sarah Page. The race is on to track the creature down before it hits the streets of London.

Cutter's research leads to a prediction about where the next anomaly will appear. But when Jenny, Connor and Abby check out the location, all they find is an abandoned house. They wait to see if an anomaly will appear, but get more than they bargained for when they discover a camouflage beast from the future is living in the house.

Some cute but surprisingly dangerous burrowing creatures called Diictodons nearly cause a disaster at a hospital when an anomaly opens from the Permian era. Calamity is averted by the team, which manages to get the creatures back to their own time whilst simultaneously delivering a (human) baby. Meanwhile, Helen and her army of 'Cleaner Replicas' attack the ARC.

The team battles to save the crew of a 747 aircraft from a Giganotosaurus.

The team must find a way to stop a flesh-eating fungus that takes over any human it encounters.

The ARC is invaded by the military; the team is set on by a flock of "terror birds."

A medieval knight comes through an anomaly in pursuit of what he believes to be a dragon.

When an anomaly opens at a race-car test-track, the team must draw on all its skills to capture and return a lethal, giant carnivorous insect from the future. Things become even more complicated when Abby's brother Jack inadvertently goes through an anomaly to escape the Megopteran. The team sets out on a rescue mission and find themselves in a future world filled with terrifying predators.

The team must deal with a herd of embolotherium from the Eocene which do not budge easily.

When the anomaly at Johnson's headquarters reopens, Sarah and Becker head off to check it out. Helen decides the only way to stop the destruction of life on Earth is to stop humans ever evolving and goes back in time to kill Hominids, the very first humans. The rest of the team must stop Helen at all costs.
