The only thing more terrifying than Snakes on a Plane is “Snakes on a Submarine,” and that’s exactly what we get in this claustrophobic, sub-aquatic thriller starring Luke Perry. Lieutenant Commander O’Neill (Perry) was piloting a retired submarine to its final port when Admiral Wallace (Tom Berenger) diverted the crew for one last mission: rescue an imperiled army research team before they meet a watery death. In order to reach the researchers and their top secret cargo while avoiding detection by a hostile enemy fleet, Lieutenant Commander O’Neill orders his crew to “run silent” in the depths. That silence is soon broken, however, when the cargo proves to be two genetically altered leviathans. Now, far beneath the ocean floor, a new kind of predator emerges to prove just how vulnerable man truly is when there’s nowhere left to run.

In 2007, in the midst of the drought and water shortages, the NSW State government has unveiled plans to tap into and recycle millions of litres of water trapped in a network of abandoned train tunnels just beneath the heart of Sydney. However the government suddenly goes cold on the plan and it is not made public why. There is talk of homeless people who use the tunnel as shelter going missing, even though the government states that there are no homeless people in there. This, and the silence from the officials and ministers, leads a journalist, Natasha to begin an investigation into a government cover-up. She and her crew Pete (Producer), Steve (Cameraman) and Tangles (Sound Technichian) decide to investigate the story in the tunnel.
