Primeval - Season 5

When a nuclear submarine encounters an anomaly and a Liopleurodon in the sea, the team are called aboard to help. They soon find themselves under attack once more, and get sucked back through an anomaly, with Liopleurodons damaging the outside of the sub. The team must not only capture the panicked Eustreptospondylus aboard, but fix the sub exterior in order to get home.

Matt finds himself in Victorian London having followed a displaced raptor through an anomaly. Realizing it's to blame for several gruesome murders in the area, he tracks it down only to find Emily attempting to do exactly the same thing. Despite attempts from an angry mob and her own husband, Emily and Matt are forced through the anomaly with an angry raptor, where Emily is forced to make a tough decision about her future.

Philip and Connor secretly open an anomaly within the ARC, only to be invaded by a mass of scurrying future-beetles, who force the ARC into lockdown. The team have just moments to save the day before both the ARC and the beetle threat are destroyed by Philip's drastic plan.

With increasing numbers of anomalies running the ARC team ragged, Matt realizes his mission is coming to a climax, and determined to stop Philip, races to his machine. The team, meanwhile, are struggling to keep up with demand. When Philip escapes Connor's custody, the clock is ticking for them to stop him in his tracks.
