Episode 2
The ARC team are called after a nuclear submarine encounters an anomaly and a Liopleurodon in the sea. While Abby examines a raptor-like creature which the sub crew have brought on board, Connor looks for a way to lock the anomaly. Unfortunately, the sub is then attacked by a group of Liopleurodons - and the craft is sucked through the anomaly, getting damaged in the process.
