Primeval - Series 4

It's one year on and following the death of Johnson, the ARC has been shaken by the long-term disappearance of Abby, Connor and team leader Danny. The government has appointed entrepreneurial-scientist Philip Burton to take charge of the operation, with a brand new building and new team. Ex-soldier and zoologist Matt, the highly efficient if unconventional Jess, the mysterious Gideon and anomaly-travelling Ethan all join the team, but are they ready for the challenges ahead?

As Connor and Abby finally escape the terrifying creatures of the Cretaceous to an uncertain welcome back at the ARC, Danny continues to fight his way through a Pliocene age Rift Valley, desperate to return to the team with a vital secret that will change their whole outlook.

With a new team and new creature threats, the ARC team are facing their toughest challenges yet…
