The Guillotine

1,000 feet under the surface, Prehistoric Anthropologist, Ash Barrington, and his team are in the midst of a great archeological dig at the bottom of Lake Superior where they find a treasure trove of bones. Bones of dinosaurs that aren't supposed to be in this particular region. In their underwater facility, Infinity Moon, Ash and his team soon discover a series of underground tunnels. Upon exploring, they accidentally open an ice pocket, thawing the prehistoric creature trapped inside. Soon they are being attacked, the facility falling apart around them, by what Ash knows is a dunkleosteus and all those bones were from its prey. Now...Ash and his team are the prey and the creature will stop at nothing to get to them.
