The team split up to face two threats. Danny, Abby and Connor travel back to the future determined to stop Helen before she can hurt anyone else. Meanwhile Sarah and Becker must head to Christine Johnson’s headquarters where an anomaly has re-opened. In the future, Danny, Abby and Connor find Helen, but she manages to escape through an anomaly. Connor works out a way to follow her and they endure a harrowing journey back through time via several anomalies, encountering future predators, raptors and pterasaurs along the way. At Johnson’s office, Sarah and Becker come under attack by three vicious megopterans. At first they try to fight these dangerous insects, but when Becker loses his weapon in the battle, they have no choice but to run. During Danny, Abby and Connor's prehistoric travels one of them comes face to face with the earliest humans, hominids, in an encounter that will change their life forever.
