Still suffering from Cutter's loss, the team must swing into action when the biggest anomaly they have ever encountered registers on the detector.
It turns out the ARC team aren't the only ones with access to an anomaly detector - journalist Mick Harper has stolen one of their handsets. One step ahead of our heroes, Mick and his boss, Catherine Kincaid, lie in wait at the airecraft hanger where the anomaly has appeared, ready to record whatever comes through.
Unfortunately for them, what comes through is a truly terrifying predator. The Giganotosaurus AKA G-Rex is huge: think of it as T-Rex's bigger, angrier cousin.
As the G-Rex terrorises the journalists and the trapped crew of a 747, the race is on for the team to get the over-sized meat-eater back through the anomaly. Unexpected help comes frmo Danny Quinn, who turns up at the scene and refuses to leave.
