In this program, Len Goodman, a judge on "Dancing with the Stars," discovers how the impact of the Titanic disaster is still felt a century after the ship sank. Goodman has his own connection to the ship. Before he was a dancer, he was a welder for Harland and Woolf. This was company that, from 1909 to 1912, built the Titanic in Belfast. Goodman worked for the same company 50 years later, at their yard in East London. To mark the centenary of the Titanic tragedy in 2012, Goodman explores the ship's 100-year legacy. He learns how for victims' families and for the survivors themselves, the sinking was just the beginning of the story. Generations later, those stories are still unfolding as Goodman meets the modern-day descendants to learn how, 100 years after it sank, the Titanic's legacy lives on.
