A vicious burrowing creature brings chaos to the city, forcing the team to race from location to location to try and trap it. In the creature's final attack one of their own is in the line of fire and the team must fight to save their life.

When a nuclear submarine encounters an anomaly and Liopleurodon in the sea, the team are called aboard to help. They soon find themselves under attack and get sucked back through an anomaly, with Liopleurodons damaging the outside of the sub.

Following a displaced raptor through an anomaly, Matt ends up in Victorian London. Realising its to blame for several gruesome cuddles in the area, he tracks it down only to find Emily attempting to do exactly the same thing. Meanwhile, back at the ARC, Abby knows she has to try and reconnect with Connor; they've been spending too much time apart.

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 the ARC and the beetle threat is destroyed when Philip threatens to incinerate the building.

The exhausted ARC team struggle to cope as more anomalies are opening. As the whole team lets Lester in on the secrets of Matt's mission, they're interrupted by worrying news - anomalies are opening everywhere and there are reports of a huge creature loose on the streets. Matt knows this is something important - the time he's been waiting for is now.

Connor has disappeared through Philip's anomaly, and Matt thinks that his mission is over, Philip has won. But he can't leave Connor to his fate and jumps through the anomaly only to find himself in a barren desert world, with Connor struggling in the immense heat and deadly sun's rays.
