For nearly two months, the USS Newark, carrying an experimental, top-secret military cargo, has been lost at sea. When the sub is finally discovered sixty miles off the coast of California, the government, eager to regain the lost cargo, assembles a highly-accomplished salvage team, accompanied by Dr. Carly Ryan - head of the original project - and her assistant. Unaware of the danger lurking within the sub, the team is sent in to recover the cargo and determine the cause of the ship's disappearance. Written by psycroptic
