At a bombing range, a worker sets a bomb to destroy a test-tank. He heads back to the viewing facility, and sees that his partner is dead and has a huge, clean-cut slash through his stomach. The worker calls his boss about the death, but no one answers. In the background, a raptor runs to the tank - unseen. He turns to view the tank and sees the tank is destroyed, but he hasn't even detonated it yet...
When the ARC team arrive, the Achillobators have made the viewing center into a makeshift nest. The terrified worker is shivering behind a desk, hiding from the raptors. He hears one screech, and he almost screams but his mouth is covered by Matt. The raptors sense movement and attacks the team. But Becker distracts the creature, the 20 foot raptor starts to run towards him, very angry.
He EMDs it, but the raptor barely slows. Then Matt throws a chair from the viewing area at the raptor and turns and starts running at Matt. Becker quickly EMDs it twice, then it finally drops unconscious. However the other raptor attacks Abby and Allison, but Ben quickly EMDs it.
Achillobator has ran out the viewing center and is headed for another test-tank. As the team see it running, another raptor raises its head out of the tank: there's a whole pack of raptors. The team run out of the viewing center and all circle around the tank. The raptors aren't coming out, they'll have to go in. Becker opens the hatch and climbs in. He doesn't see any raptors, so he calls for the team to come in. Then he notices a massive, torn hole near the back of the tank in the dark. The team climb in, along with the frightened worker, and view the hole. It leads underground, so the raptors must be down there.
