Andrew-Lee Potts, Hannah Spearritt and Ciarán McMeniman return this week with the fifth series of time-travelling dinosaur drama Primeval, exclusive to Watch.

In the first episode of the new series, an underground creature brings chaos to the city, forcing the team to chase around the city to track down the movements of this vicious burrowing creature. When the creature strikes for the final time, the team find one of their own in mortal danger and fight to save their life.

Episode 1 airs at 8pm on Tuesday 24th May on Watch. In the meantime, here are ten teasing lines of dialogue from the episode…

» “Yes, I’ve got an anomaly for you Jess – the greatest anomaly known to the western world…”

» “You’re a smart guy, but you’re wasting your time.”

» “This is about Phillip. I need to know what’s going on in Prospero.”

» “You know what Matt? Trust has to be earned.”

» “What you are about to see is not ARC business. You may not discuss it with anyone.”

» “The anomalies are a resource. We’ve been so distracted by the creatures that we haven’t noticed!”

» “We need guns. Lethal weapons.”

» “Just so I know, who is it exactly that Matt intends to shoot?”

» “Look, at the risk of sounding self-involved, this had better not screw up my knighthood!”

» “If you’re going to be part of this, you need to know what you’re dealing with. I need you to help me.”
