In 2005, a History Channel expedition team locates large sections of the Titanic's bottom hull more than two miles under the Atlantic, over 1,500 feet from the main wreck site. The pieces are well preserved enough that the ship's original red paint is still visible, and no one had closely examined them before this dive. The film uses that footage, gathered in high definition, to test whether these fragments change the standard account of how the ship broke apart and sank. Analysts and engineers work through the wreck's structural evidence, comparing it against the long-accepted version of the disaster that killed more than 1,500 people in 1912. The case built here is about sequence and mechanics: what separated from the hull, when, and what that says about the ship's final minutes on the surface before it went down. It stays close to the deep-sea footage and the physical evidence rather than restaging the sinking as drama.
