It’s June 2019, and Tim Taylor and his team are looking for a U.S. submarine that disappeared in mysterious and tragic circumstances. They’re using a remotely controlled underwater vehicle to help in the search, but as the machine travels through the depths, it frustratingly develops a fault. So, Taylor brings the craft back to the surface and takes a glance at the data that it’s recorded. Then he spots two strange inconsistencies that prompt him to send down yet another probe. And what the technology finally unearths is enough to make the hairs on your arms stand on end.
