The older daughter tries to use the boat radio to call a mayday, but because the mercenary crew is on an illegal expedition, the company man stops her, and she ends up going overboard and he refuses to save her. The father, his younger daughter, and the boyfriend all jump overboard to save the older daughter and stick together. ScarJo gets a sample of the Mosasaurus’ DNA, which was one of the three specimen they need.

The spinos chase the mercs to the beach, where one that was already sleeping there eats the other girl besides ScarJo. The mercs proceed inland and gets a DNA sample from a Titanosaurus. Meanwhile, the family walks through the jungle and ends up sleeping on the ground for the night; the boyfriend wanders off to take a piss and is almost ambushed by two raptors before the Mutadon, a raptor/pteranodon hybrid, picks them off. The family later finds a raft they can use to traverse the river and get to the island’s research complex. The T-Rex attacks them in the river, but they manage to survive.

Meanwhile, the mercenary crew climbs to the pterosaur nest and acquires a DNA sample from an egg, but another of the mercs gets eaten, leaving ScarJo, Ali, Company Man and Nu-Grant. They go for the same research complex, where ScarJo has arranged for a helicopter to extract them. They run into the family and she exposes Company Man for trying to kill her. The others turn on him, so he pulls a gun he stole earlier and prepares to kill the family when two mutadons fly down and attack everybody. Company Man steals the DNA samples and escapes in a jeep, leaving the others behind.
