Episode 5.4 (Primeval)

Connor uses his device to open an anomaly within the ARC. The team come to close it, but are ordered out of the laboratory by Philip who heads to "New Dawn" to collect data from the device. Connor tells Abby the purpose of the anomaly. Back at the ARC, a swarm of future beetles and their enormous queen come through the anomaly and kill a guard before spreading throughout the building after chewing through reinforced concrete. The ARC goes into lockdown trapping Matt, Connor, Abby, Becker, Emily and Jess inside and they are forced to fight for survival. Jess is bitten by one of the beetles and has a reaction to the bite, slipping into unconsciousness while the team's initial plan to poison the creatures fails. Connor says he can trigger a gamma ray burst from his anomaly but Matt has already disabled the computer control. Matt is forced to reveal that he and Abby have a copy of the data on Connor's computer and they then use it to sterilise the ARC while they take cover in a panic room. Becker gets Jess the adrenaline she needs while Connor discovers that Philip had tried to incinerate the ARC with the team inside, and that he had been in communication with Helen Cutter.
