As the ARC team still reel from Stephen's death, they are joined by several new team members, including new security leader Captain Hilary Becker, and sparky egyptologist Sarah Page. Meanwhile, after discovering a future world where the Earth is overrun with Future Predators, Helen Cutter sets out on a mission in the present against the ARC, whom she blames for the future catastrophe, and launches an attack on the ARC in which Nick Cutter is killed by Helen. The ARC subsequently manage to obtain a mysterious artifact from the future from Helen, which in turn causes military liaison Christine Johnson to target the ARC and attempt to take control of it and get the Artifact for her own purposes. Following Cutter's death, the ARC team are ultimately joined by ex-cop and new team leader Danny Quinn, and Jenny Lewis learns of her alternate life as Claudia Brown and ultimately leaves the ARC. Meanwhile, Connor himself is forced to move out of Abby's flat and into Lester's (to the latter's chagrin and misery) when the troublesome Jack Maitland moves in with Abby. As Johnson's mission to get the Artifact from the ARC continues, Helen returns and kills Johnson. When the ARC team learn that Helen intends to wipe out humanity's ancestors to stop them evolving to cause the future disaster, Danny, Connor and Abby are sent on a race after her through the Anomalies. Helen is killed before she can kill off enough of humanity's ancestors to have a temporal impact, but Abby, Connor and Danny are themselves left marooned in the past.
