There’s an extra-thick jeopardy sandwich to tuck into this week. What begins with the team investigating an underwater anomaly turns into an international incident. And it’s not enough for a pod of liopleurodons to be attacking the damaged nuclear sub that Matt, Abby and Connor are aboard; there has to be a vicious young theropod sneaking around the vessel, too.

ARC HQ’s takeover by trigger-happy Navy goons gives an appalled Lester (Ben Miller) the chance to fire off some snappy put-downs, although name-checking Dr Strangelove doesn’t excuse the gung-ho, Commando comic dialogue. There are solid thrills and spills, all the same.

About this programme

2/6. When a nuclear submarine encounters an anomaly in the sea, the team is called aboard to help, only to come under attack from aquatic reptiles and be transported back to prehistoric times. With external damage to the sub and no electricity, Connor, Matt and Abby face a struggle to repair the craft for the journey home while fending off the marauding creatures. Back at ARC, Lester has to cope with Navy bigwigs threatening drastic action if the crew cannot fix the problem. Sci-fi adventure, starring Andrew-Lee Potts, Hannah Spearritt, Ciaran McMenamin and Ben Miller.
