No tale inspires shipwreck hunters more than rumour of priceless treasure lying on the bottom of the sea.

Such ships have been found, but few as unique as the 1999 discovery of the Vrouw Maria.

Caught in a storm in October 1771, the two-masted merchant vessel, en route to St. Petersburg from Amsterdam, struck a rock and sank along with her cargo of fine Dutch art for Russian aristocrats.

For nearly 230 years the vessel lay undisturbed on the seabed with little decay due to the Baltic's brackish nature.

Teams of deep-water detectives use today's cutting-edge technology to make a shipwreck "tell its story."

Each hour-long episode investigates one underwater mystery, told through fascinating underwater footage, CGI graphics, expert interviews, archival materials and dramatic re-enactments.
