Groundbreaking documentary which follows a Japanese-led team of scientists as they attempt to shed light on the mysterious world of deep sea sharks. Only 50 specimens of the newly discovered 'megamouth' have ever been sighted. Over four years, scientists and film crews voyaged in midget submarines into the depths of Suruga Bay and Sagami Bay to film them. Prehistoric 'living fossil' sharks such as bluntnose sixgill sharks, goblin sharks and frilled sharks also lurk in the depths. As part of the investigation, a sperm whale carcass was placed at the bottom of the sea to attract these sharks, which were then studied and observed from the submersible vessels. Revealing in detail the previously unknown behaviour of deep sea sharks, the film unravels another of the intriguing mysteries of our planet's biodiversity.

Documentary about the sinking of the Britannic during the First World War, examining how she ultimately came to suffer the same fate as her sister ship, the Titanic. The Titanic sank in April 1912, and her sister ship, the Britannic, ultimately suffered the fate, sinking in 1916 due to an explosion caused by an underwater mine. In the wake of the Titanic disaster, Britannic was re-engineered to be even stronger. And yet she sank in just 55 minutes - three times faster than Titanic. It's one of Britain's greatest untold disaster stories. Now on the 100th anniversary, presenters Kate Humble and Andy Torbet piece together exactly what happened in those 55 minutes. While Andy makes a dangerous dive to the wreck, Kate speaks to descendants of the survivors. The characters she uncovers include Violet 'Miss Unsinkable' Jessops, who survived both Titanic and Britannic, Captain 'Iceberg Charlie' Bartlett and lookout Archie Jewell, who miraculously survived while those around him died.
