A secret that went down with the Titanic, and a race across the globe to find it...In the vast expanse of the Atlantic, 375 miles off the coast of Newfoundland, a ships crew film an extraordinary event: the ocean, covered with millions of floating fish, bubbles as though boiling. Then an enormous whale roars through the water and crashes down, dead, onto the surface. Some 13,000 feet beneathat these precise coordinateslies the wreck of the Titanic. Within 24 hours, the video has become a global phenomenon. Commander Jerry Derham, charged with investigating the incident, rushes to see marine archaeologists Kate Wetherall and Lou Bates. The one-time couple specialize in deep-sea-diving and the scientific study of shipwrecks. Jerry needs to get the pair down to the ocean floorfast. None of them are prepared for what they find there. Someone on the Titanic had been keeping a secret: one that cost lives. It has remained trapped beneath the ocean for 100 years, and now there are those who would kill again to get hold of what one man died for in 1912.
