At the start of the fourth season of Primeval, we find it’s been one year since the death of Johnson (Belinda Stewart-Wilson) and the ARC has been shaken by the long-term disappearance of Abby (Hannah Spearritt), Connor (Andrew Lee Potts) and team leader Danny (Jason Flemyng). The government has appointed entrepreneurial-scientist Philip Burton (Alexander Siddig) to take charge of the operation, with a brand new building and new team. Ex-soldier and zoologist Matt (Ciaran McMenamin), the highly efficient if unconventional Jess (Ruth Kearney), the mysterious Gideon (Anton Lesser), and anomaly-travelling Ethan (Jonathyn Byrne) 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.
Seasons four and five of Primeval have been released on a four disc “volume three” DVD set. It includes all 13 episodes, as well as a featurette about reviving the series and the prequel webisodes.
