A young girl searching for her dog ends up stuck on the other side of an anomaly, leading Cutter and Stephen to mount a rescue mission into the sandy deserts of the Silurian.

As the three of them fight for survival, Cutter realises they are not alone: someone is actively trying to sabotage their work.
